I love Costco. If I were ever to be trapped in a store for 24 hours, Costco would be my choice because basically everything you ever need is in their warehouse. Their products are all great quality for great prices, but it's all in bulk, so it's not good for single people. If you are single, try gathering up all your other single friends so you can split things (I mean, who really needs 40 giant rolls of toilet paper?). Costco is famous for offering free samples of their food products; my favorites are when they offer samples of stuff from their deli and bakery. They're also famous for their food service stations, with a hot dog and a soda for $1.50 being their best seller. You can also get pizza, chicken bake, salad, and ice cream. There are no words for how much I love Costco--I'm there practically every weekend!
