Target is ending its guarantee to price match Amazon and Walmart on July 28. A spokesperson for the retailer confirmed the policy change to USA TODAY. Beginning July 28, Target will only match its own in-store and online prices at Target.

After more than a decade of promising “unbeatable value,” Target is walking back one of its most customer-friendly policies. Starting July 28, the retailer will no longer price match Amazon or Walmart — ending a 12-year run that allowed shoppers to snag the lowest price if they could prove a better deal elsewhere.

Shoppers will no longer be able to buy an item for a lower price if they can prove that they found an identical product listed for less by Amazon or Walmart.
