I have earnt over £many £0000's with Quidco over the past 12 years. They used to be very good, but it seems these days with larger purchases there are often problems, for example with IHG Hotels. They pay out but not at advertised %. When the amount claimed is in the 000's this matters. Their customer service is useless, and email discussions just die. Sometimes there is simply no excuse why payment has not been made. They don't dispute the % advertised, but pay out on lower %. It is interesting the small amounts always tend to be paid without an issue! I am afraid i don't trust Quidco!
