Home Depot Canada has a mail in rebate form you can print and fill out. You will get $7 back on each 3.78L can of paint you buy, or $25 back on each 18.9L pail you buy on qualifying paints. Qualifying paint brands are BEHR, CIL or Martha Stewart Living.
This rebate is good for internal and external paint, primer or stain. See the rebate for all details.
Qualifying paint purchases are from April 21 to April 27, 2011. You must send in your rebate by May 27, 2011.
I think this is a good deal because paint is rather expensive. If you are painting an entire room, or your entire house this can add up to some serious savings.
