Are companies that sell prescription drugs without prescriptions legitimate?

Are companies like Pharmacy Network legitimate sources of medicine? Has anyone purchased drugs from this site or others like it with success?

Yes, some are legit. The reason they don't require prescriptions is because the meds they are selling do not require prescriptions in THEIR country. I have bought from http://www.4rx.net and http://www.xlpharmacy-rx.com for years and have never bee disappointed.
Prescriptions are a U.S. tactic to make doctors money, and a way to keep prices up on medications for the major drug companies, by calling them "prescription medications". As U.S. citizens we have been brainwashed to think prescription strength means stronger.
For example, look at Claritin. It stayed "prescription strength" the entire 10 years that no one in the USA could make a generic, but when their 10 year exclusivity ran out, it magically became "over the counter" and became cheaper, why? It all comes down to getting more money from Insurance companies. The problem is, people without insurance suffer! And those with insurance suffer from higher premiums.
