There are very few that can even process free trials, let alone make them work after paying $20-30 per sign up to the webmaster.
Most went to $1 trials because (I assume) it's easier to prove the auth for the recurring transaction if there's an original charge on the CC.
I like both & my surfers seem to like them as well, so if the program/site is good enough to make their money back after the PPS costs, then everyone is happy
