This site has a listing of different pharmacies, but a lot of the information is outdated and inaccurate. Plus, it appears that they receive commissions from the pharmacies on their "recommended" list. Also, there are indications that they blacklist some pharmacies not necessarily because they are scams, but rather because they got into disputes with them over payment of these same commissions; i. E. "pay us more money or we will blacklist you!". My advice is to pay attention to the more current reviews of any particular pharmacy without putting too much stock into whether or not they've been "blacklisted".
