OT: MS voucher

Tue Aug 22 12:10:06 PDT 2006

I received a Micro$oft Voucher for $96 from the California Settlement, 
Does anyone knows if I can use this voucher on new purchases ? It reads... 
Proof of purchase for the products that you bought after July 18, 2003.

So that means I can go buy a wireless mouse and it will meet the criteria 
right ? Or Do I need to find the receipt that only God knows where is it 
of the product I bought 1 year ago ?
