On July 31, a Reddit user shared some intel on a product favored by both Costco-lovers and chocolate chip cookie-makers: Kirkland Signature chocolate chips had been replaced at their local store. “They completely replaced the chocolate chips with Nestle,” wrote u/SomeRealTomfoolery in r/Costco, showing a rack of Nestlé Toll House Semi-Sweet Morsels in 72-ounce bags in a Costco store. The post went viral with more than 500 reactions and 160 comments. On July 3, one Redditor posted a screenshot of a message they say was sent by a Costco representative explaining why its buying team made the switch. In the letter, the alleged representative cites rising costs as a reason for the discontinuation.
