One of the more larger Costco Wholesale chains I have been to, the Costco located in Fullerton is one of my favorites. As always the pricing there is very competitive. Also, besides just the great selection offered there, there is a food court located outside of the wholesale department and an optometry center where you can get your eyes checked or get new glasses. Everything about Costco is fantastically convenient. You have to buy membership though, otherwise this place is the best place to shop wholesale.
