I am continuously looking for ways to cut my grocery bill for my family of four. We love fresh fruits and veggies, which as a rule, can be pretty expensive. I love the idea of a CSA, primarily because I think supporting local farms is so important, and secondarily because the idea of getting the freshest, locally grown produce is intoxicating to me...however, I'm wondering if it makes sense for my wallet, which has felt the ever-increasing squeeze of this horrible economy. If you are part of a CSA, what has been your experience? Do you find that it saves you money in the long or short run? Is it expensive? Do you end up with more wasted, unused produce? Has it cut your grocery bill?
