I don't have any disposable income for crowns right now, but I do have credit in my amazon account. I thought I'd see if I could pick up some discounted crowns though them (I couldn't, shocker) but I did notice I could pick up Morrowind, something I hadn't done yet since I considered it a little too expensive for an expansion pack. I thought I might as well preorder it when I noticed this annoyance

I do not have the Steam version of ESO, I have the regular, downloaded from site version. I assume then that the preorders Amazon is selling are useless to me then? Or would the key still work if I put it into the ESO account management page instead of steam? I don't know any other game that does this, but hey, might as well ask.
