For several years I've had good success with xlpharmacy.com and have been pleased with their service and product. But the last couple of times they've failed to fill my order. They didn't charge but also didn't fill it. Placing an order on their website is almost impossible. I'd really appreciate any advice on sites that are safe, reliable and inexpensive. Thanks

Viagra is stong medicine, and you want to be sure you are healthy enough to take it.  You also will never know for sure if you are getting the real thing if you get it over the net.  There is a lot of counterfeit pharmaceutical out there these days.

To save money, however, ask your Dr. to write a prescription for the largest size, then use a pill cutter to chop it into halves or even quarters.  The pills cost the same regardless of size.

For genuine Viagra, try netdr.com.  They ship promptly, and the price is reasonable for on-line pharmacies.  I agree with mrfisher that you should talk to a doctor first and that the best price would be at your local pharmacy.

Sage and sound advice....Go to your primary provider (MD that is) S/he knows your health better than an on-line pharmacy. There are side-effects which can ply havoc with other health issues.
