I have a small CSA. Two lovely women are bartering 4 hours per week each in exchange for a "share" of food each week. It's a really common CSA practice around here and works nicely all the way around.
Just registered today! I'm in VT and I LOVE to barter. Newest barter this week: trading a trio of 4 month old NZ/Cali breeding meat rabbits for 10#plus country cured pasture raised ham.
