hmmm good idea!

dispenser.tf

Yes.

URL alone smells incredibly fish-like. :/

interesting.ill have to check this out

i dont know if i would use a site like this. especially because if the site goes down or something all your credits mean nothing.

Something else to consider. I've seen this done a lot on Magic: The Gathering Online. The person that runs the bot makes money because often times people will not use all of their credits. Lots of people with 0.5 credits leftover adds up. Also, some people will sell things to a bot before making sure that a) the bot will in fact buy everything you have to sell and b) the bot is selling things you want at a reasonable price. I realize this is a bit different, but I think people will get the idea after reading my post. They will be beholden to the system.

Also, like others have said, that url screams stay away.
