Thanks. The wholesale market was an afterthought, since the original idea was not going to be completed by the submission deadline. The original idea was to allow the player to assign a certain percentage of each "crop" to auto-sell to a farmer's market (i.e., auto-sell 50% of the wheat, and keep 50% of the wheat for making sandwiches).
I'll probably get that working in a future update as well.
Thanks for playing!
