Yeah its only a few western states, but I am sure if you look in your area you could find something like this. Basically this co-op pools money and buys produce and other goods at wholesale prices and divvies them up, there are other costs involved with buying, coordinating and delivery of course. For $15 we can get 2 laundry baskets of fruit and veggies, we can also buy stuff in season at a discount and freeze or can. Like last year we got a case of corn, cooked it in salted water, chilled in ice water and froze. Way better then any other corn in the freezer and came out to $.20 per quart bag.
This is also a great way to get out of the house and meet others in your area, I knew one guy who got a good job from the networking that he got from it.
The only “bad” thing is that every week its completely different stuff. So you will get things that you never heard of or seen before. We love it for that reason, those who are picky may not.
