From what I understand, drop shipping is when you purchase from someone who doesn't have the product but contacts a 3rd party to ship it out. I personally only use domestic vendors but I get a feeling, during correspondence, that I'm talking to a British vendor. Who then, I assume, has a connect in the US that ships it. - what do you think? Am I talking out of my ass here or is there some legitimacy to what I'm saying?
I think if you're selling very popular drugs that have lots of vendors it'd be pretty easy to do this. For example since Abraxas went down there has been a massive influx of meth vendors. The vast majority of the meth market is heavily impure and/or cut. Many vendors charge $75 a gram of equal quality (or lack thereof) meth that another vendor sells for $50:
Not saying this is common, but just a thought.
