Has anyone had any experience buying contracts through Omio and their third party sites? I'm going to stay away from the cash back things, and stick to the automatically reduced contracts. Are they legitimate?

Yes, comparison websites are legit. The make a small free from directing users to a 3rd party website. I know these deals do seem too good to be true.

The cashback by redeption that you are referring to does have terms & conditions attached and therefore are not as straightforward as you think.

best-mobile-contracts.co.uk is another such comparison website, they offer the ability to remove these "redemption" deals from the results.
