I understand just starting out.
But that license price is just a pass through to the customer, just like all the other hardware.
Regarding fleabay...
A guy selling a Win 10 Pro license (or RAM/GPU/whatever) that he no longer needs for cheap is one thing. No problem.
A guy selling 1,000 of them...you have to ask...how? Where did they come from? What special channel does this guy have from Microsoft where he can sell them at 80-90% discount?
Answer - He doesn't. Just like the rest of us.
What he DOES have is a pile of licenses that were obtained from Not For Resale avenues. Corporate, edu, MSDN, whatever. Not for resale.
Corporate licenses in particular are widely sold like this. They will initially be fully activated and appear valid. Of course, 180 days from now...after not being able to talk to their corporate license server, they WILL time out. I had exactly this happen with a laptop from Newegg last year. Result, a highly irate customer, me. The
reseller on Newegg is on my permanent DoNotBuy list. For anything. Ever.
Or outright money laundering.
If someone were to obtain 500 stolen credit card numbers, how to turn that into actual cash? Not with physical goods...that requires a physical address, shipping, and paper trail.
Digital goods, OTOH, only needs an email address and paypal acct.
If you want to sell PC's on the up and up, lay out the options for your customers, and the actual costs.
Win 10 Pro = $XX, Win 10 Home = $YY, or install it and leave it Unactivated $0, and let the customer sort out his own licensing.
And inform them the options and features of each choice.
Further from fleabay:
