Have been a member here for more years than I care to count.
Sam's is full of bargains and deals... if you purchase in large quanities. Not everyone wants to buy 48 rolls of toilet tissue or fifty pounds of rice at one time though.
They have excellent pizzas that you can take home to bake, or have them bake them right there for you.
Large selection of meats also. They also have bakery style sheet cakes for celebrations that are very inexpensive.
There is a pharmacy, optomotry, and a large selection of videos, computers and accessories.
