Heads up on something I found yesterday.
I ordered Sky online yesterday, on the value deal plus unlimited broadband. This is £27/month, with a free Sky+ box and installation. I was also inline to get £25 M&S vouchers.
I found that I couldn't use my Introduce a Friend otherwise I would be charged £79 for the Sky+ box and installation. So I went via Quidco ( which entitled me to £40, £25 on the Sky+ and £15 on the broadband) and ordered.
The next day I was emailed saying that my order had been cancelled because they couldn't contact me via phone (which is rubbish as I never got a call!).
Anyway, I rang up to find out what was going on and they explained that they couldn't find the order, so it was cancelled. I explained that I will re-order via the web to get the Quidco and the guy spoke to his manager and offered me £45 credit on the account to cover the Quidco, which I accepted.
We then carried on through the order and he also gave me a Sky+ HD box (it wasn't HD on the website) and confirmed the IAF code worked, so I ended up with a HD box and £100 M&S vouchers (split between myself and the friend).
Might be of use to anyone who doesn't want to wait for Quidco to pay out ...
