Is Amazon Fresh cheaper than Walmart Grocery in the USA?

Usually, Walmart Grocery is cheaper than Amazon Fresh for a typical U.S. grocery basket, especially on pantry staples, store-brand items, household basics, and price-sensitive weekly shopping. Amazon Fresh can still be competitive or cheaper on some sale items, Prime-exclusive deals, private-label products, and when convenience or fast delivery is worth more than the lowest shelf price.

Best practical answer: if your main goal is lowest total cost, start with Walmart Grocery. If you already use Prime and value delivery convenience, compare the full cart total in both apps before checkout because delivery fees, tips, minimums, substitutions, and local promotions can change the winner.
