I just came across this neat website. It's called Websaver.ca. Not only do they offer a coupon for a FREE Box of Chocolate Cheerios (YUM!) right now and lots of other coupons, but they also donate 0.5 cents to Breakfast for Learning from each coupon ordered from their site, that is actually redeemed. Watch out though, you can get the FREE Box of Chocolate Cheerios on one day only, June 21 2011 - so keep that coupon safe and don't forget about it!
You do have to register, but it's quick. Next time they have a great offer or you want to re-order coupons, you can just sign in. Enjoy!
