Usually when I need or want some food item, I want it in relatively short order. If I'm out of Cheerios, I don't want to wait for 30 other people to also run out before I can replenish. Groceries are one of those areas of commerce that run on extremely slim margins. I think that by the time you covered all the overhead of aggregating, managing, and distributing the bulk buys you'd end up with nothing left over. Plus, you are dealing with perishable goods for a good part of the product base. This makes proper handling and the dependence on functioning coolers even more critical. Most business models these days are trending towards cutting out "middlemen" that don't provide a significant value-add. I don't think saving $50/mo. (taking a theoretical stab at an estimated savings) would be worth all the hassle to most people, there is too much potential for frustration.
