I'm going to a local craft fair at a nearby high school and will be attempting to sell photos. There will be local craft people selling all sorts of things and lots of parents and teachers associated with the school so I think there is a good potential to make quite a bit of money. I'll be offering my prints at reduced prices compared to my website to encourage people to buy. I've arranged around 40prints at 15 x 10 as samples and will take 2 or 3 30 x 20 framed images as props. I was planning on recording customer's details and arranging prints once the order is in rather than gamble on lots of orders and receiving none. I'd then post the images to the customer. I've pretty much decided on my pricing but was wondering if anyone had any pointers on what to do/no do or say/not say? If i'm asking for full payment up front am i likely to reduce my sales? I'm only talking about prices around the £20 so it's not hugely expensive. any advice would be appreciated.
