I do buy meds online, even prescription pet stuff.

My vet won't fax to them due to the high fraud rates. The practice is happy to give me the script, and I scan it and attach it to an email, after I place my order. I put the order number in the email. Works fine, and LOTS less money.

Ellie is SO right, you do have to verify that it is the same medicine. I also get my flea meds from Australia, but I've been advised by my vet that it is a different product as the bugs they have to address are different. Hmm, I've not had any trouble though.
