There is no single chain that is cheapest for every shopper. Walmart says its prices average 10–25% below competitors, but that is a Walmart corporate claim rather than a neutral, four-chain basket test. Your actual total depends on ZIP code, package size, loyalty pricing, digital coupons, promotions, fulfillment fees, and substitutions.

For coverage, Walmart is the clear national leader by reported U.S. locations. Kroger operates more supermarkets than Albertsons Companies (which includes Safeway), while Albertsons/Safeway offers a large loyalty program and broad pickup and delivery availability. The reliable way to choose is to compare an identical basket at your local stores under the same account and fulfillment assumptions.

What the latest figures actually show

The chains do not report their footprints in identical categories, so unit counts are useful context rather than a perfect head-to-head ranking. Albertsons Companies reports all banners together, including Safeway; Kroger reports supermarkets; Walmart reports several store and club formats.

Company or banner group Reported U.S. footprint Measurement date and scope Other reported scale
Albertsons Companies (including Safeway) 2,244 stores in 35 states and the District of Columbia February 28, 2026; 22 banners, including Albertsons and Safeway 36.5 million customers per week; delivery from more than 2,200 stores and Drive Up & Go pickup from more than 2,100
Kroger 2,697 supermarkets in 35 states and the District of Columbia January 31, 2026; supermarket count from its fiscal 2025 Form 10-K Approximately 63 million households served annually
Walmart U.S. 5,217 total retail units: 3,569 Supercenters, 351 discount stores, 674 Neighborhood Markets, 21 small-format units and 602 Sam’s Clubs July 31, 2026; Walmart location-facts page 5,200 stores and clubs within 10 miles of approximately 90% of the U.S. population

A University of Michigan RSQE presentation lists 2025 primary-store shares of 24.8% for Walmart, 11.8% for Kroger, 3.2% for Albertsons and 2.3% for Safeway. Those percentages provide market context, not a substitute for each company’s own location count.

Why a universal “cheapest” answer is not reliable

A grocery price is an outcome of several variables, not just the shelf tag. Two stores can have different totals even when they are in the same ZIP code, and the ranking can change from one week to the next.

Store geography and operating format

Rent, labor costs, local competition and distribution routes differ by market. A large suburban supercenter may price staples differently from a smaller urban supermarket. The nearest location may also carry a different assortment or package size than another branch of the same chain.

Brand, size and unit price

Comparing a 12-ounce package with a 16-ounce package makes the lower shelf price meaningless. Record each item’s brand, flavor, count, weight or volume, then compare the unit price. Private-label products can also differ in ingredients and package sizes, so “store brand” is not automatically an identical product.

Loyalty pricing and digital coupons

Albertsons, Safeway and Kroger commonly show member prices or digital offers that require an account or loyalty card. A shopper who does not clip a coupon can see a different total from one who has already loaded it. Include the same account status and coupon treatment in every quote.

Promotions and timing

Weekly ads, multi-buy offers and personalized discounts expire. A basket checked on Monday may not match one checked on Saturday. Save the date and the offer terms with your comparison.

Fulfillment costs and substitutions

Online pickup and delivery can add service, delivery or small-order fees, and a substitute can change the brand, size or price. Compare in-store totals with in-store totals, or compare online carts using the same fulfillment method and fee assumptions.

Walmart’s price claim—useful, but not a four-chain test

Walmart’s U.S. location page states: “Walmart’s prices are, on average, 10–25% lower than those of competitors.” This is the company’s own positioning statement. It does not identify a standardized current basket, list every competitor, or establish that Walmart is 10–25% cheaper than Albertsons, Kroger and Safeway in your town.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use the figure as a reason to check Walmart when price is your priority, not as proof that every item or every market will be cheaper. A local comparison should supersede a national marketing average.

Albertsons and Safeway: one company, two familiar banners

Safeway is one of the 22 banners operated by Albertsons Companies. Treating Albertsons and Safeway as independent national companies would double-count the parent company’s footprint, although shoppers still encounter separate local banners, assortments and weekly ads.

Coverage and services

Albertsons Companies reported 2,244 stores across 35 states and the District of Columbia as of February 28, 2026. It said delivery was available from more than 2,200 stores and Drive Up & Go pickup from more than 2,100. The company names Instacart, DoorDash and Uber as delivery partners. Availability, fees and delivery windows can vary by ZIP code and store.

Loyalty scale

The company reported 51.2 million loyalty members in fiscal 2025, up 12% from the prior fiscal year. Its filing says loyalty and digital data support personalized offers and pricing or promotional decisions. That can make the effective price attractive for a shopper who regularly activates offers, but the benefit depends on the items you buy and whether you maintain an account.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

When the banners can fit best

  • A nearby Albertsons or Safeway is substantially closer than alternatives.
  • Your regular basket matches the chain’s member deals or digital coupons.
  • You value curbside pickup or delivery and the local store has the needed inventory.
  • The store’s fresh departments or private-label products fit your household better than a lower-priced substitute.

Kroger: supermarket scale with very high card attachment

Kroger’s fiscal 2025 Form 10-K reports 2,697 supermarkets in 35 states and the District of Columbia as of January 31, 2026. Kroger says it serves approximately 63 million households annually.

What the loyalty statistic means

More than 95% of Kroger customer transactions were tethered to a Kroger loyalty card, according to the filing. That indicates loyalty pricing is central to how customers shop there, but it does not tell you that Kroger’s final basket is cheaper than another chain’s. The value depends on the card price, coupons, product mix and redemption rules that apply to your cart.

When Kroger can fit best

  • You shop often enough to use member prices and digital offers consistently.
  • A Kroger supermarket is your closest full-service option.
  • You prefer a supermarket trip with pharmacy, fresh departments and a broad weekly-ad assortment in one location.
  • You can compare advertised deals against your actual list rather than chasing discounts on items you would not otherwise buy.

Walmart: the broadest reported footprint

Walmart lists 5,217 U.S. retail units as of July 31, 2026. The total includes 3,569 Supercenters, 351 discount stores, 674 Neighborhood Markets, 21 small-format units and 602 Sam’s Clubs. Walmart also says 5,200 stores and clubs are within 10 miles of approximately 90% of the population.

Check the specific store’s grocery departments, pickup times and delivery radius rather than assuming every format stocks the same items.

Rewards information is not directly comparable

The cited Walmart location information emphasizes everyday-low-price positioning and footprint. It does not provide a directly comparable grocery-rewards membership figure in the same passage as the Albertsons and Kroger statistics. Do not treat Walmart’s price positioning as evidence that its rewards structure works like a supermarket loyalty program.

Rewards comparison: what to measure instead of member counts

Question Albertsons/Safeway Kroger Walmart
Reported loyalty scale 51.2 million members in fiscal 2025 More than 95% of transactions tethered to a loyalty card; approximately 63 million households served annually Comparable grocery-membership figure not stated in the cited location information
How discounts may appear Member pricing, digital offers and personalized promotions Card-linked pricing and digital offers Everyday-low-price positioning; program details are not established by the cited passage
Best comparison question How much do your clipped offers reduce your normal basket? How much do card prices and redeemed offers reduce your normal basket? What is the out-the-door total for the same items without assuming a comparable loyalty benefit?

To evaluate rewards fairly, track the dollar value actually redeemed over several trips. Also record whether offers expire, require a minimum purchase, apply only to a particular brand or size, or can be used once per account. A large membership base does not guarantee that your household will receive useful offers.

How to run an honest four-chain price comparison

A repeatable test is more useful than a generic national ranking. Run it for the basket you actually buy.

  • Use your Visa Gift Card in the U.S. everywhere Visa debit cards are accepted, including online.
  1. Choose one ZIP code and four specific stores. Use the locations you could realistically visit or whose delivery areas include your address. Record the store format and date.
  2. Build an identical item list. Specify brand, flavor, package size, count, weight and acceptable substitutions before collecting prices. Include a mixture of staples and the products you buy most often.
  3. Decide your loyalty assumption. Either compare advertised non-member prices everywhere or create and use the normal free account at each chain. Do not apply a Kroger, Albertsons or Safeway member price to a Walmart total.
  4. Apply coupons consistently. Load only coupons available to the test account on the test date. Record multi-buy requirements and limits, and do not count a future reward that cannot be used on this transaction.
  5. Capture unit prices and package differences. If an exact size is unavailable, mark the item as unavailable or choose a predeclared equivalent. Do not silently compare different quantities.
  6. Choose one fulfillment method. For an in-store test, exclude delivery and pickup fees. For an online test, use the same method at each chain and include service fees, delivery charges, minimum-order fees and tips as separate line items.
  7. Handle substitutions transparently. Note every replacement, its size and price, and whether you accepted it. A substituted premium brand can reverse an apparent savings.
  8. Record taxes and fees. Use the same tax jurisdiction and disclose whether taxes are included. Keep a screenshot or receipt so the result can be reproduced before promotions expire.
  9. Repeat for more than one week. A single sale cycle can favor one chain. Repeating the same basket across several dates shows whether a difference is persistent or promotional.

How to interpret the result

If Walmart is lowest before discounts

That supports choosing Walmart for this basket and location. Check whether the result depends on a larger store format, a private-label substitution or an item temporarily on promotion. If travel is longer, add the value of time and fuel before declaring an overall winner.

If Kroger or Albertsons/Safeway wins after loyalty offers

Measure the discount you actually redeemed, not the headline value of available coupons. A chain that wins only when you buy extra units may not be cheaper for a small household or a shopper with limited storage.

If totals are close

Use convenience as the tie-breaker: distance, parking, pickup reliability, delivery fees, pharmacy access, fresh-food quality and the likelihood that your complete list is in stock. Saving a few cents can cost more in travel or an extra trip.

If one chain cannot supply the full basket

Report both the complete-basket total and the missing-item count. A low subtotal with several unavailable products is not equivalent to a one-stop shop. You may prefer a slightly higher total that avoids a second store.

Common comparison mistakes and fixes

  • Mixing banners and parents: Albertsons and Safeway belong to the same Albertsons Companies footprint. List the local banner separately for shopping decisions, but do not add their stores together as independent national competitors.
  • Using national averages as a guarantee: Walmart’s 10–25% statement is a corporate average claim, not a promise for your ZIP code. Verify with your basket.
  • Ignoring account requirements: Member prices disappear if you do not identify yourself at checkout. Include enrollment and login steps in the test.
  • Comparing advertised prices without purchase limits: A “buy five” deal may require five qualifying items. Apply the minimum and maximum exactly as written.
  • Leaving out fulfillment costs: Delivery and pickup can change the ranking. Put fees, tips and substitutions on the same worksheet as item prices.
  • Comparing different dates: Promotions expire. Timestamp every cart and do not combine prices collected weeks apart.
  • Confusing store count with practical coverage: A chain’s national total does not tell you whether the nearest branch has your preferred departments or delivery window.

A practical decision framework

Choose the chain that minimizes your total cost and friction for the trips you actually make:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Start with availability: eliminate stores that are too far away or cannot fulfill your normal list.
  2. Run the same-basket test: compare identical quantities with a clearly stated loyalty and coupon policy.
  3. Add trip costs: include delivery, pickup, fuel, parking and the value of an extra stop.
  4. Evaluate reward fit: favor discounts you can redeem on normal purchases, not theoretical points or coupons you rarely use.
  5. Check consistency: repeat the test on another promotion cycle before changing your regular store.

For many households, the answer will be a split strategy: Walmart for a broad stock-up when its local total is lower, Kroger or Albertsons/Safeway for targeted member deals, and whichever store is closest for urgent fill-in trips. That is not a contradiction; grocery prices and convenience are local and basket-specific.

Bottom line

Walmart has the broadest reported U.S. retail footprint and claims average prices 10–25% below competitors, but that figure is not a neutral comparison of Albertsons, Kroger, Safeway and Walmart. Kroger reports 2,697 supermarkets and more than 95% loyalty-card attachment; Albertsons Companies, including Safeway, reports 2,244 stores, 51.2 million loyalty members and extensive pickup and delivery coverage. Compare the same products, package sizes, dates, accounts, coupons and fulfillment method at your local stores to find the chain that is actually cheapest and most useful for you.
