I currently use Online Google Docs to collect Preorders and payment for preorders for my novels that I sell at book conventions, fairs, and other events. I offer a discounted price for the orders, and the reader collects the prepaid books at the event. I can add their email address to my contact list manually, but google docs are not very flexible and have a clunky look.
I'd love a replacement for Google Docs preorder forms that I can post online on the book fair event group for readers on Facebook. Besides the seamless integration with my contact list, the nicer forms will stand out in the crowd of authors with preorders!
