I just got a flyer in my rewards check from Staples Office Supply - this is a good deal on Paper (if you print alot like I do)
Valid 4-25-10 to 5-22-10 - Spend $40 on any combination of case or ream paper and get $25 back in Staples rewards - Min purchase of $40 in cases and/or reams must be made in the same transaction to qualify. Maximum benefit of $50 back in Rewards for the promo. Limit one Staples rewards account per person. Offer not valid on single or multipart computer paper.
If you order online or over the phone you would have to spend $150 per the flyer - so in the store would be best I guess.
They give an example in the flyer of Buy HammerMill CopyPlus Case $40.99 - less $25 you will get in rewards back - actual cost of the case becomes $15.99 after rewards rebate.
Remember to print out the Email cpns that staples sends out weekly that say "good only online or over the phone" - they always accept them in the store for me - they simply enter the code into the computer and it takes it.
So a deal might look like:
2 cases of paper $40.99 = $81.98
less $25/$75 printed email cpn
making oop $56.98
Then get back $50.00 in rewards
So Two cases of paper for $6.98
