Just seen this whilst looking at other bargains on the Tesco threads. Seems a good deal although I don't have one so can't vouch for its quality. Basically its a DAB tuner that plugs into your hifi via its aux input. Apparently it has a remote control as well. http://direct.tesco.com/q/R.202-0345.aspx
Was £49.99 now £12.49

You can get half price del by adding a £2.47 sim card (which has free del) and there are some codes for £5 off £20 spend. Also I think you can get quidco on this too.
