it works on bc.com and dept of goods, they are different stores though so you have to click through each store on the rebate site. like clicking through for bc.com will not work for dept of goods. you would have to search dept of goods when you are signed into mrrebates and click through, it will pop up and send you to deptofgoods.com so there is no confusion.
steepandcheap does not have rebates.
what i do is go to cashreporter.com and search for the store i want and it will tell you what rebate site is offering the highest % back.
i would stay with only mr rebates, shopathome.com, fatwallet, ive used coupon cactus too, but stay with the ones that do paypal payments or send you a check - usually the sites that are on cashreporter.com are legit. it is not 100% guaranteed that you will ever get the rebates, i believe one site called cashbaq closed and left everyone hanging. so i look at it as just extra gravy on top, i dont really base my purchases on it, it is just a nice treat once the rebate checks end up in my mailbox. it only takes a couple extra clicks so why not.
