Microsoft does not sell windows 8.1 Pro licenses, but is it on sale?

Question

Windows

Local software vendors cannot sell licenses for win 8.1 pro due to the lack of such on sale and argues that Microsoft leaves only the latest versions of products on sale. And there are no boxes or electronic esd licenses for sale. And I believe them.
But at the same time, many online stores sell win 8.1 pro esd and even Office 2010 esd. And these stores are not ephemeral and exist for several years, which inspires confidence.
Where do they sell something that microsoft does not sell in a hedgehog?
Microsoft Windows 8.1 Professional (x32/x64) All Lng (electronic license) [6PR-00006]
or Microsoft Windows 8.1 Professional LE 32-bit/64-bit 6PR-00006 is written in the title,
Google says that 6PR-00006 is a boxed version (FPP -license).
