Windows 8 for $14.99 upgrade? (Need to buy a Windows 7 desktop though)

I was wondering if such a thing was ever worth it. Would you buy a Windows 7 desktop, then upgrade it to Windows 8 for $14.99. I don't think you should considering the fact that I could save more money just by upgrading Windows 8 by buying it for $190. I don't know about you guys, but do you think that this offer is worth it? Just go to this url and read this article about more info on upgrading 'cheaply'
