Do I have to pay to join a cashback site?
No, there are a large number of free to join cahback sites such as Greasypalm and Cashbag who are free to join and will reward you for shopping through them. There are also a few cashback reward sites such as Topcashback, Quidco and Mrs Cashback that do require you to pay a joining fee and in return for paying this they offer to pass on a larger share of the commission rebates that the receive.
