The ShopRite in Hackensack refunded me the full price I paid for elephant garlic, $3.49, when I returned to the store today and pointed out the sign in the produce section said $2.99 on the day of purchase. It still said $2.99 today. (See earlier post: "Another fast one at ShopRite.")
I had feared I was going to get only 50 cents back and didn't want to make a sepcial trip. But an errand brought me near the store and I had tucked the receipt in my wallet just in case.
I applaud the store for its full-refund policy. The Englewood ShopRite, owned by a different company, used to give full refunds for overcharges, but abandoned the policy years ago.
