I am sure that like most things I do, this will be in actuality different from how my mind now sees it.
However, of all the things I do to make money (detailing cars, running the carwash, fixing things), ordering things for the vendor and stocking it seems pretty easy.
Besides, when it's time to re-order and re-stock, those are good problems to have because it means you've sold all the items you are trying to sell!
Let's see; buy a can of soda of 25 cents and sell it for a buck. Uhhh, that's a pretty big incentive for a small-potatoes guy like me to order some stuff on the phone and open the vendor and put it in there.
I would've never made it this far in business if I thought that was 'too much work'.
