Don't forget....a simple email or phone call to your fav companies can result in some great coupons! Start by complimenting their product that you like and use then ask if they happen to have any coupons for loyal customers or if they could point you in the direction of some. I have received a bunch of coupons by just asking. But please remember DO NOT abuse this or companies will stop doing this. I have a general rule of requesting no more than 2x/year.
And please share your success stories here so others can try too!
