You should be able to do a free upgrade to 8.1 from 8 by visiting the Store on the start screen anyway, so you'd be paying for something you can get free, just in a slightly less convenient manner (the upgrade may take a few hours from the beginning of the download to having a usable desktop, after you've already done a proper installation of 8.0). In that sense, probably not.
