Seeking Rx Advice--

Does anyone have an on-line pharmacy they like, or one that does overnight shipping, that offers very competitive prices on name brand drugs? In three weeks I need to buy Bicillin L-A, a med that comes in vials and is injected into the muscle. It retails for something like $432 per ten vials.

I have an extremely high deductible. I've checked Canadian pharmacies, but they don't mess with things that need refrigeration. Bicillin is now owned by Monarch, and they don't have a patient discount for people on limited incomes.

I will crack CDs if necessary, but I thought I should explore Internet options. (Costco in town was only $5 cheaper.)

Suggestions?
