Hi Valerie: Interesting convo! I had a friend who sold beautiful jewelry at craft fairs, and this was her top complaint. Some craft fairs would charge crazy vendor fees simply because they were so popular. She was always worried that she wouldn't make enough of a profit. One thing she did to up her sales was to get a free card reader for her smart phone (I think she used something from Paypal). Her sales went through the roof when she gave people the option to pay with credit/debit cards, rather than just cash.
