TopCashBack

Unlike some others this cash back site has no annual fee, no minimum payment, no fees for withdrawing.  You can't lose.  A tip is to have two different browsers, one you like best and one you use for topcashback.  When you make an online purchase swap browser, login to TopCashBack and go to the site to buy the item.  That way you have a fresh cookie which tracks back to TopCashBack.
