I avoid the free trials too, b/c it's too easy to forget to cancel them...which, of course, is what they're hoping for!
Here's another coupon site, although I've not heard of it before, so can't vouch for them. Still, w/ the price of meds today, it's worth a try. If I decide to use them, I'll be sure to write about it.
