We are part of a similar subscription based system here in Belgium. Prices are somewhere between supermarket normal and organic. Mostly local, but some stuff is shipped in when the local crops really suck. Indeed forces you to learn to cook and enjoy whatever weird stuff happens to be growing well locally. This results in less effort deciding what to buy, but more effort figuring out what to do with whatever you received. I really don't think giving consumers ~more choice is going to help solve the problem of getting people to eat whatever is growing locally.
