There are a lot of legal places online where you "send" your prescription, etc. and your meds come to you. My husband's company plan was that way, his meds came from Iowa every 4 months I think. I wouldn't order illegally though because you couldn't know what you you would get. My daughter-in-law did get an expensive US drug from Australia for 1/3rd the cost (illegal) but that was through someone who had done it/knew about it that they trusted.
