Hello Kitty Tumblr Themes Free

How can my online customers donate to me?

I have a tumblr website where I create themes for people who own sidekicks. All my themes are free of charge, but I would like to know how people can donate to me. I do not own a credit card. The website is skthemes.tumblr.com if any of you are interested in any 08 or 09 themes. Most of my themes are hello kitty so i can attract customers, but I also have others. Anyways, it would mean a lot if I could find a way to have my customers donate to me. Thanks for your future help.

Definitely go for a paypal account, then get a donate button
