I use this whenever I shop online. It lets you get cash back from couponcabin as well as using online coupons. They have special offers for extra cash back but they are limited to two a month. I took off a star because my husband tried to use the service too and he was blocked as a duplicate account. It was insulting and he wont try it again. I also use other sites because cc does not have cash back for every retailer. I will say this is the best cash back for shopping online site I have used. Other sites often do not record the purchase and then you have to claim and wait. Cash back is almost always automatic added to my PayPal.
