Cashback sites - UK
I'm sure many people already use cashback sites, but if anyone is not aware of them they are a way of getting cashback when shopping online. Often the cashback is a small percentage of whatever you spent, but sometimes there are larger amounts available (in the £10s or £100s) of for things like insurance or mobile phone contracts.
These sites are a good way to get a bit more cash for hardly any effort.
Does anyone know any others in the UK or elsewhere?
