here is a list of sites to check frequently. they are online coupon sites, and they usually reset at the beginning of the month. many of the coupons listed can be printed twice, unless they are reset mid-month, and there's no way of knowing ahead of time which ones will reset. check them, and then recheck them if you find a coupon that you love.
