We have a lot of information on our pharmacy lists, most sites have their own information page.
It is free and it is available at:

http://www.drugbuyers.com/freeboard/ubbthreads.php?ubb=pharmacylist

We have a U.S. List, a Canadian List, and International List, and a Black List

We also have an "all-in-one" comprehensive US list that contains contact info, names of doctors, and pharmacies, and a lot more: www.drugbuyers.com/members/list

Please visit them before ordering. It is a good idea to visit our lists and the message boards prior to placing any orders...
