then maybe they aren't negotiating hard enough on our behalf?
If they're getting £50 for us for a phones4u contract and Topcashback are getting £65 then surely we're all better off with Topcashback? Plus there's no annual fee so you're £5 better off because of that each year, and you can refer friends to get £2.50 which quidco don't offer. And they match other offers, so if you find quidco offer more for something then they'll match it.
The only thing is I don't see how they make any money? Surely doing this they are just going to make a loss?
Then there's cashbackkings (from rpoints) who offer pretty much the same thing, no fee, top rates of cashback with a promise to match others on request. Referral fees paid to you (£5 for 2 members I think).
They also offer £65 for phones4u.
So maybe it's time to drop quidco?
