What sort of insurance does she have? Is this a one-time prescription, or a chronic thing? Many plans now include prescription delivery by mail.

I don't think she has any and it's a chronic thing. They've been buying the medication locally but the pharmacist apparently suggested recently that some of it could be found cheaper online. In my research so far some of it is available online but the narcotics definitely aren't.

She might want to check with her insurance company. A lot contract with companies like Medco to deliver fomulary drugs directly to clients.

The controlled substances might be a problem anywhere. My company ships controlled substances worldwide, and we have a ton of paperwork to prove it. We stock most narcotics, but you don't want to pay our prices.

The following websites have good reputations, but you probably checked them already.

Drugstore.com
walgreens.com
cvs.com

The National Association of Boards of Pharmacy has checked out and approved several sites. The list is here.
