Sorry - but the 25 off 100 is ONLY for 100 dollars of clearance items defined as:
ORDERS MUST INCLUDE one or more item that has a price that ends in .96 or .97 or .00 (this indicates that the item is CLEARANCE PRICED) $25 off an order of $100 or more after rebate (net of any coupons or other discounts) excluding gift cards on a single transaction receipt, for orders made at TigerDirect.com, TigerDirect.ca, or the mobile sites of either brand.
Your plan works - but not for the 25 off 100
