Key word there is paying. A buck is fine with me, but I don't have a good way to offer it. I'm not giving you my credit card number, email or phone number; I'm not going to spend even 10 seconds filling out a form just for your site; I don't use PayPal; I don't currently authorize you to ever take any more than the buck I want to give you right now; I want a refund if the functionality doesn't work as described.
Has anyone made any real progress in solving this problem?
