GFS Marketplace is similar to Sam's Club. The main difference between the two is that GFS just sales bulk food and is free to shop at verses Sam's which is $40 a year. Right now GFS is only on the east coast but, they are expanding west.
This location is in Monroeville next to Kohl's and across the street from Monroeville Dodge and Sam's. They offer every type of food product in bulk you could think of. Meats, seafood, produce, snacks, stuff for fundraising, desserts etc.
Some things are cheaper than Sam's. And some aren't but, they are defiantly worth checking out.
