Its a lot of work but I guess it all counts
Its a lot of work for small amounts. The good is you build up some money to overpay your mortgage. The bad is that shopping normally you build up tiny amounts. I noticed that my sister was getting double the rates I was getting (not on a boost) and asked sprive why. They wont provide any sensible explanation so it seems that different people get different cashback rates which is not really fair. Overall- it does do what it says but im not sure its worth the hassle- for the rates im getting at least.
