Listen to all the above advice and don't give the "bad guy" next store a second thought. You are a consumer who purchased an advertised product with no inkling of whether the seller is operating the business to the letter of all applicable laws. For that matter, law enforcement itself hasn't mangaged to clarify the legalities of the so-called "grey area" of Internet Medicine, so no more is expected of you.

If the DEA wanted to make a bust, they wouldn't come to your house, they would go to the loading dock of the hotdeals places as they pack 30,000 orders of medication into the UPS truck each day. Some truly huge number of Americans (which I won't quote since I don't have the figure handy) have purchased medicine over the internet.

Like the other posters on this thread, I'm a real smart guy, so listen to us

So sleep soundly and pain/anxiety free,
