Have we really never talked about CSAs on this list? Correct me if I'm wrong, but if not we should definitely discuss.
CSAs (Community Supported Agriculture), in case people aren't sure, is a kind of farm coop where you purchase a share in the farm and then receive a portion of the harvest every week. I'm sure there are variations on the model, but that's how ours works.
We tried this for the first time two years ago and we're completely hooked. The food is local, organic and (best of all) FRESH, always having been picked that morning on the farm. It's also introduced us to some new veggies (like mizuna, hakurei turnips, and celeriac), and taught us what's in season when.
We are with Sauvie Island Organics (http://sauvieislandorganics.com/). We pay $770 for one share for the entire season. One share feeds 4, and the season runs from May to December. Obviously, you don't have enough veggies at the beginning and end to do without supplemental shopping, but in the peak season it's delicious veggies coming out your ears. I've had to learn to do some preserving, even.
Our farm also offers additional options like farm-raised eggs, salad greens, and flowers. We don't have any fruit except for melons, which might be a dealbreaker for some people. I just figure that's what I'm allowed to buy at the farmer's market...
They have bulk drop sites where you show up at a designated time every week and pack up your food, and they also have the option to have a drop site where they leave a pre-packed box and you have a bigger pickup window (there's an additional cost for this). We've done both and they both work well, but in general I'm very pleased to see how they've expanded the drop sites over the years. It's much more convenient.
Anyway, I guess this is a pitch for them because we've loved them so much, but also I'd love to hear about others' experiences, good or bad. I suppose we could also talk about if/how you like delivery services like Organics to You.
