our reps at epoch and ccbill tell me those more expensive trials lead to chargebacks, so you might wanna watch out for that. we did the most sales with the $1.95 and $2.95 prices - this did especially well with search engine traffic.

but higher priced trials - anything over $4.95 - sold less than 5% more than full month memberships for us so we made a lot more money dropping the trials.
