I, too, am selling cupcakes at my local farmers market. It gets pretty good traffic, but could someone with experience selling baked goods at their farmers market help me to estimate how many people I should plan to sell? Should I plan on 10% of the traffic buying baked goods? Or plan on 100% of the people? I don't want leftovers and I don't want to sale out early. Any help would be great! Thanks in advance.
