Recommend me your favorite online-shop pls! I'm confused about amount of shops in internet

What are you looking for? Be more specific, please. One of the best choices is to see your health adviser before buy some of those products.

Just becareful when ordering those. First I thought you need a prescription for those pharmaceuticals?

If your doc has verified that this med is really safe for you
you can save some money if you order meds online, just check the pharmacies very careful before you buy anything.
Here are some tips from my experience with online drugstores.
One thing I know for sure - do not buy anything from a pharmacy that sends spam emails, I know a few guys who been ripped that way, including
myself. Also avoid pharmacies that have got well known SCAM products on their product lists (like penis/breast enlargement pills, viagra for women and other questionable "products") It is a very big chance that their prescription meds are also fake.
When you have found something that looks like a good and trusted pharmacy, check if the pharmacy has got a live support chat or a support phone number. If you have any doubts I suggest to contact the support staff before placing any orders, because if your shipping will be delayed or if there will be any other problems, it is better you have already tested the quality of support they can provide. Also ask the support what are their shipping and refund policies.
Order Viagra online probably is one of the cheapest sites online. Have ordered a couple times, the meds work ok, just as the ones I can get at Wal Mart. It is from the UK and I feel much better ordering from a British pharmacy than a pharmacy from India or Mexico.
