Here's What Happened When I Returned a Half-Eaten Package of Cheese to Costco
My Costco membership is something that easily pays for itself. Not only do I more than make up the cost of an upgraded membership via the money I get back on Costco purchases, but I save more than $120 a year on groceries alone by virtue of shopping at Costco. One of the reasons I love Costco -- aside from the savings opportunities -- is that its customer service is really outstanding.
