Where to buy windows product key

[BiggerBluer]

Ok I'll try to make this short. I'm building a new pc this summer and was wanting to know where would be the best place to buy a windows product key from. I plan on not having a dvd drive in my pc so I'll be using a usb download of windows. I have never done this before and was curious if once I downloaded the files from the usb would the software allow me to buy the key or do I need to buy a physical disc with a product key from like a best bey or something. Thanks for the help

Keys must be bought with disks. Anywhere that sells keys alone is shady at best.

So all disc versions of windows come with keys? Sorry this is a really noob question but I have never installed windows on a new pc.

Yes, all disks MUST come with keys, otherwise the disk is useless.

Save yourself the headache and buy from reputable online retailers like Amazon, Newegg, etc.
