If you're just buying this as a cheaper way to get Windows 10, buy windows 8.x pro licenses. They're cheaper and you get a Windows 10 pro upgrade.
I found this one on Amazon for $65.00: http://www.amazon.com/gp/product/B0..._m=ATVPDKIKX0DER&pf_rd_r=0CPSN6Y0ZRC75E4ER9K9
Keep in mind that, although this way is cheaper, you will be going through the built in MS store to update to 8.1 (takes a few hours), and THEN updating to 10 (also takes a while).
I have a windows 8 license/disk and I downloaded 8.1 from MS and directly installed 8.1 using my 8 key.
I suspect you can directly upgrade from 8 too, but I don't know.
Windows 7 Pro is still the best OS (for me) I won't leave it until I have to. You can have your WIN 8 & 10. No Thanks!
