Go to drugbuyers.com and check out the lists, US, Canadian, International and Black lists (illegit pharmacies). There used to be more international/cheaper vendors, maybe they'll come back sometime. Don't get your hopes up for any good opiates like Hydrocodone...looks like only US pharmacies have those which require consultation. Overseas pharms have your Valium, Xanax, Klonopins, Ativan, Soma..look into each carefully and read the feedback.
Remember you need a perscription to purchase these medications or they risk getting seized by customs. ::wink wink::
