Costco: Upgrade three computers to Windows 7 Home Premium for $135

446871 If you have a Costco membership and three computers that you want to upgrade to Windows 7, then you can get a giant wooden palette of operating systems for $135 – this same three-pack is priced elsewhere at $150 while a single version of the upgrade runs $120.

I’ll let you do the math on this one but needless to say, it ends up being a pretty good deal for a multi-computer household. You may also consider getting the three-pack from Staples and using one of the store’s relatively ubiquitous “$30 off a purchase of $150 or more” coupons if you happen to have one of them in your possession. That’s an even better deal, although you’ll need to track down the coupon of course.
