If you login to TCB and click on Three Mobile link there are certain tariffs where you save £3pm+ plus you will receive cashback. In the case of the 8gb, 600mins, unltd texts, Feel at Home deal you receive £50 cashback too so that makes it £12pm - poss £50 cashback. Great deal even without cashback. Note, you must login to TCB and click Three link. There are others as mentioned. I went for the 8gb deal.
