Saw over at Neowin that electronics retailer Micro Center is offering Windows 7 pre-orders for $10 less than the pre-order standard prices.
>> Micro Center offering Windows 7 coupons for $39 and $89
There is a catch though, you have to go visit one of their 21 US locations to obtain a coupon between today and Sunday. However, once you've obtained the coupon you can then return between October 22 and November 4, after Windows 7 will hit general availability, and purchase your copy of Windows 7 for the reduced price. Meaning you don't have to actually "pre-order" right now, just obtain the coupon and purchase later.
