Anyone know of a good way to get Windows 7 at a discount?

My current copy of Vista is a Vista 64 Basic "update" edition, so I'm not going to be able to update it to Windows 7. It would be a pain to do so anyway ... I'm running Windows 7 Beta, so I'd have to uninstall it, install XP, upgrade it to Vista, then upgrade that to 7.

I do not have access to any student discounts, and it's probably still over $200 with my Employee Purchase Program (which seems pretty worthless).

Thanks,
