CPA Free Trial Offers

Okay I've got some good ones at Copeac - but does anyone know of any other Free Trial offers at other networks?
I'm specifically looking for ones where if they sign up for the free trial of whatever product it is - and they cancel later, they dont have to send it back.

Ah - I'm part of 50% of those...and the majority require returning the product if the person cancels after the trial. Like say, TriSlim trial bottle. Its only at Copeac that I've found the ones that don't require it.

But! Thanks for the list. I'll go apply at the other 50% to take a look.
