Are you a college student? If so, your college or university might have a discounted software program. These won't be in the same retail packaging as you'd get from a computer store or e-tailer and will come with restrictions. Occasionally you'll see a few dollars marked off of the retail price or some sort of bundled deal with other hardware but there's no deep discounting these. Even XP, where you can find it, isn't at fire sale prices.
No OEM and no Upgrade.
Full retail version.
Can't find anywhere cheaper than $179. Is there a student discount I can use somewhere?
