There are all sorts of variations on similar scams.
I've had calls from various people with some challenging to understand 'accents' claiming to be from Texas in need of some fairly 'generic' industrial equipment I supply. They want to pay by credit card and want it air freighted over night and it doesn't really matter the cost just "get it shipped". When you're in Texas, the "oil belt", these commodity items are sold at any industrial supplier. When it's even pointed out to them that these $4000 worth of components they can pick up for about $2000 locally, they don't want to hear it.
That's when you use a bit of your business accumen to make sure they have a nice day and move along.
Sounds like a prudent thing to do to be a little suspicious. Anyone who wouldn't be, I think would be a little naive.
