Personally I’ve found generic levitra to be extremely inexpensive and to work very well. Half a pill works for 48 hours for me, which is at least two pumping sessions. It was only 95 cents per pill, so 47.5 cents / 48 hour period, I don’t think it gets much cheaper than that. Doubt you’ll find that kinda deal, best I’ve encountered but I’m sure you can get something relatively close.
