I have used Top Cashback now for some time and regularly check if there is cash back on the retailers I may use. It certainly makes sense to check this site as cash back can soon add up and if you are going to order at a retailer why not apply via Top cashback as you have nothing to lose. It is also great to check the amount of cash back on offer for different retailers that may supply the same item(s) so you can order from the one that provides the overall best price when cash back is taken into account. I have found the process very straightforward and worthwhile.
