Can U enter $ that isnt marked??

Can we post any money or does it have to be stamped?

By all means, post every bill you can get your hands on. Then add the URL by neatly writing on it, fine point Sharpies are popular. And if you get hooked like most of us here, consider buying a stamp!

The whole idea is to get hits. I don't thing youll get any if you don't put the web address on the bill. I mean woulden't you like to know where your money goes?
