Have had a few problems trying to use vouchers once purchased. You go into the relevant website to spend the voucher but twice I have had this isn’t a correct voucher and this is on 2 separate websites. So I have found the whole process very frustrating and for the amount I have credited to my mortgage, I’m not sure whether it is worth the effort and I will be deleting Sprive app. Overall the concept is good but they need to look at how you claim vouchers.
