I am not 109% certain if you can do this or is willing to do this but I was just wondering if there is the possiblity to have other payment methods rather than using PayPal. Some people may want to buy stuff but don't have the means of a PayPal account.
I can add this to our worklist of possible future things to work on but I am not sure if that is something that can be done in the near future. I'll have to see what @Sbenny says.
