If you MSN Passport then go to wallet.msn.com and then sign in with your passport. Click on the Participating sites (Stores list) then click on Officemax. While in OM site use the checkout using MSN wallet to check out your item instead of using OM checkout button. This way MSN wallet knows that you bought the item. Ofcourse you have to give ur CC info to MSN. Now MSN would give 20% back as MSN Dollars that you can spend on future purchases starting Feb/March 2003. Somewhere i read on the MSN site that for a fee of $3.00 you can close your MSN account and Citibank would send you a check for the remaining MSN Dollars. $3.00 would be deducted there. Max allowed is $100/account. 2 account per household. Offer expires in 6 days i guess. More info visitMSN Wallet
Those three items should get you over the $150, so take off $30, $40 rebate for the Palm, $10 rebate for the phone, and $10 rebate for the CD-Rs, and if my math is correct, it should come out to around $64+tax with free shipping.
I also used the MSN wallet, so I have credit for around $26 available February.
