Tobor,
They are Food Distribution Centers ran by the Church, The LDS are known for having products "at cost" or really close to the cost. So you wont find that 30% markup that is everywhere else. I like using them because I know I am not supporting China-Mart... IMO its a no brainer. Even better I believe they have a case lot sale once a month or maybe every quarter, not exactly sure. I do the case lot sales at the base once a month, save quite a bit in canned food alone.
