Just get a home depot and a lowes credit card.
They'll send you 10% off coupons all the time. And "1 year, no interest, no payment" deals as well.
I bought all the materials for my wifes ex-house (better than ex-wifes house, which would probably be MY ex-house
) remodel that we did last year with a home depot 10% off coupon and the 1 year no pay/no int.
Note that home depot CAPS the amount of the 10% off while a lot of the lowes coupons do not have a cap.
With my marketing hat on, I believe the intent of these coupons is to get people who have just bought their first house, or a house in a new neighborhood, to come in and shop at their store in the hopes you'll like it and stick with it. They make little attempt to ensure you're actually a 'new' person or a 'new' home owner or 'newly moved' and dont seem to care much. If you 'falsely' obtain a coupon and go buy a thousand bucks worth of stuff at their store, I would feel like my marketing mission was accomplished.
Note also that you can often get a home depot or lowes manager to take the 'other guys' coupons. Hit rate on this is VERY high, especially if both have a store in the same town. Ask to see the store manager and ask him/her before you shop, and get their name. Cashier will call up to them when you check out and verify, then have the floor supervisor come over and punch in the discount. Takes a couple of minutes. Well worth it if you make large buys of 'stuff' like I do.
If you just CANT find or get the coupons and are planning on making a large buy, you can get them on ebay for a few bucks.
