Agreed with the notion that it’s not great to look at CSAs as a way to save money. As others have mentioned, they only really provide a financial benefit if your membership replaces purchases that you otherwise would have made had you not been in the CSA. Most people I know who belong to a CSA either end up with produce that they never would have bought anyway, or end up with more of something than they otherwise would have purchased. And, given that produce doesn’t stay fresh forever, I see a lot of people act as if they’re actually ‘captive’ to their CSA haul and are forced to cook/eat stuff that they really don’t want anyway.
CSAs are great ways to support your local farms and to potentially try new things but similar to gardening, the benefit is in the experience and not in the dollars.
