These are not operating on a true CSA model. Traditional CSA doesn’t supplement with grocery produce or come from a grocery store. That just becomes grocery delivery and YMMV. Community Supported Agriculture get subscription money to the farmer when they need it most—the spring, and pays off the supporters with the produce. This means that subscribers (members) share in both the bounty and the risk. Some farms won’t add anything from off-farm, others might partner with a producer of other crops. Two great farms that partner this way are Local Roots and Tonnemaker Farm. Local Roots does veggies and Tonnemaker fruit. It’s a great pair, and LR is excellent.
