KidStart: Unique cashback for kids from websites you use anyway
Edit: November 2021
For some months now, I've not found a single retailer not on other cashback sites listed on KidStart. Where retailers are on both, cashback rates are consistently higher on the other sites. I can therefore no longer think of a good reason to use KidStart. Use TopCashback, and if you want to give your cashback to your kids then go ahead - they'll get more that way anyway than if you do it through KidStart.
