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.com, if the price drops within 14 days, the spokesperson said.

Target is ending price matching of products sold for less at its competitors' stores and websites. For 12 years, Target customers who found a product that was sold for less on Amazon or Walmart's websites could request to buy the same product that was sold at a Target store at the lower price.

Target CEO Brian Cornell said in an earnings call in May that U.S. tariffs were one factor in a number of “massive potential costs” for the company. He also warned that price hikes could come as a “very last resort” after earlier in March telling CNBC that certain goods will “likely see price increases” for consumers.
