I seriously love so many things about Costco. I've had a membership there for at least 10 years. The quality of their products is fabulous. However, if something does not work like its supposed to I never worry when I make my purchase there. They have the best return policy no questions asked. I will buy things there just for that reason alone versus another store, but the prices are usually unbeatable when looking at more expensive items too so it's an all around win to buy there. Even though you pay for the membership the savings at their gas station alone are worth the price of the membership. Will be a customer for life!
