I just created an account with these folks and billed 50p to my phone in a matter of seconds.
It uses PayForIt which I've used in the past but that was the easiest m-commerce transaction I've ever set up.
If anyone has had difficulty in monetising their site this makes it so easy to put a pay wall on!
They pay 75% of the billed price in 45 days, no setup fees, no monthly fees and no messing about either.
Wins my (very hard to come by) approval, put it this way, I'm having braingasms over it!
