When you first move into a new apt/house, you (used to) get a coupon book from local stores...and Home Depot/Lowes usually had very generous discounts....
So, do you know anyone who just moved and doesn't immediately toss coupons into the trash?
Also, those stupid coupon books schools sell as fundraising in beginning of school year... Sometimes Lowes/HD have coupons in there...
Last year's book may have expired, though.
UPDATE: oh, I think you are referring to a specific marketing campaign. Sorry
