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.

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.
