Viagra may have been the first oral drug for erectile dysfunction, but it was soon followed by rivals Levitra and Cialis. Each of these drugs, plus generic substitutes, are conveniently available to purchase online. Prices can vary considerably and we suggest you take advantage of our price comparison charts before making any purchase.
Generic versions are a huge bargain, though prices have risen just a bit in recent months. The name brand pills have actually shown a slight drop in price in the same time period. Again, it pays to shop and we've compiled this information to help you get started. We've also included consumer rankings of online pharmicies as collected by "Pharmacy Shark Patrol."
