Hey, if u wanna sell ur prog without any charge.. just a small transaction fee.
Goto http://www.beseen.com

I THINK thats right. Anyways, they have a buy it button which u can register for free, and they will only charge u like 2% or something for the transaction fee.
When someone buys something they send u a check, but ur responsible for shipping it to the people.

Its not a bad idea, but they dont really give u a choice how the BUY IT button will look on ur site. O well, check it out. Maybe u'll like it.

I never used it before.
But im thinking of using it to sell my products i make, whenever i finish them.
