We are looking at doing our first festival which is outdoors. I have seen some information on the forum about festivals and picked up so good tips. Something I didn't see answered is how do some of you handle payments and receipts? We just opened our retail store a month ago and don't want to spend the money for an additional cash register if we don't have to. I never went to many arts and crafts booths at festivals and the few I did I never paid attention to what they did for handling payments.
