The Windows 10 Pro OEM COA sticker and the Windows 10 Pro OEM DVD/USB pack, are both the same except one with DVD/USB media?

One is cheaper by 50% than the other on shopee. One cost RM60 while the other cost RM120.

Are they different from those keys costing RM10 and below?

If the COA sticker the same as the DVD/USB media pack except without the media. I'm thinking of buying a few for current and future use since one media pack cost can buy 2 sticker.

Forgot to mention I'll be doing a reformat and reinstall a few times.

The current windows trial I think is corrupted but still can use except the annoying activating screen watermark, it even showup in games.
