Good SIM Only plans?

You could use Topcashback to lower the cost down a bit?

I noticed a few of these cashback deals and from what I gather the actual contract is more expensive, say £25 per mth, but then you periodically complete some online forms during the term of the contract and get cashback, making the actual contract price about say £12.

Is that it?

I guess they bank on a proportion of people not completing their online forms to get the money back, unless I've got the wrong end of the stick on what the cashback deal actually is.
