It's suggested in one of the other sites that some OfficeMAX stores will accept other store's coupons depending on the manager.
Thus the Staples
$40 off Staples Coupon, if accepted will make the cost of this drive $80 after coupon and MIR.
It's hard for me to believe that a bricks and mortar store would accept an "order on the Internet coupon" but I suppose it's worth a try. I don't think it would work here in Silicon Valley.
