That's quite a shopping list you got there Mackie.

You will probably find that the best place for Soma is not the best place for Hydro, etc.

Then you will find that the cheapest might be the slowest. Or the cheapest might want medical records or a portamedic.

So the best deal might mean Fastest / No Records, if you're in a hurry. Or it might mean just lowest-price-no-matter-how long-it-takes.

You will be looking for hydro from a consult-type domestic OP. But you might very well decide to look for the benzos from an IOP in Argentina.

However you end up defining "Best Deal" on those meds you're looking for, you should start by reading in the forums. There's a TON of information already posted, and no easy answers! Happy Hunting!
