DO NOT ORDER FROM ONLINE PHARMACIES!! I wouldn't have posted this as it seems that all responses are negative. But it doesn't look like anyone has actually tried it.
I did. A few years ago. Here is my story:
I had always been skeptical of these. I would get the spam emails and the pop-ups but figured those were all scams. So I went looking for one that was legit. I found a few, but I figured one with a good website domain had a better chance of being legit than onlineasiapharmacysellmanydruggoodprice. com. The fact that it was a httpS was a good sign too. I also thought that having slightly higher prices than those spam email sites was another good sign. I placed an order for about $40 for a few norco, xanax, viagra, flexeril, and zithromax. I figured I'd try it out and if it worked out I'd place a larger order. I went through the checkout process and as soon as I confirmed the purchase I got a notification on my phone that my checking account was overdrawn. They ran a $1 transaction, then immediately a $300 transaction. I guess it was lucky I only had $293 in my account (I still remember how much). Luckily my bank was cool about it and in 5 minutes had a new account opened, refunded my funds and moved them to the new account, and had a new debit card overnighted to me.
So I guess it all worked out in the end- No harm, no foul. I don't think I've ever told that story before.
If you're dead set on trying it, I would HIGHLY recommend buying one of those prepaid Visa cards.
