Engineer,
The white rebate form with the green printing on it says, on the left side, "Completed coupon should be sent along with a copy of the sales receipt & original UPC from packaging to:"
And on the right side, under "Terms and Conditions," it says, "Mail this completed form, a copy of sales receitp with date and purchase price clearly visible, and original, UPC code (included on packaging)...Only this certificate and invoice, together with the original UPC code will be honored. Photocopies of the UPC will not be accepted."
OTOH, at least 4 CompUSA employees I've spoken with personally have said that the limit of 1 rebate per household (printed on the rebate form but not on the ad) does not apply, and we're eligible for 2 rebates if we enclose 2 rebate forms in a single envelope.
Jackywebdesign,
I'm burning in one of those PC133 sticks at 66 MHz in my FIC PA-2007 mobo - no problems so far. I've never had a PC100 or PC133 stick not work at 66 MHz.
