Kandy
The least expensive way is ordering from Canada. There's quite afew pharmacies that sale this way. From everything I've heard they are the same as those sold here. Even a mayor from one of the States has been ordering meds from Canada for the county workers. Ofcourse the government is trying to shut it down. I haven't ordered any yet, but I have checked out a few sites & when I need to I will be ordering them thru Canada.
