First attempt at posting a deal, I'm not sure if this was just a special offer at the store I visited (The Tesco Extra in Lichfield) but I found the already discounted Magicbox Sonata C11 DAB radio/iPod dock for £15! Looking online it is still priced at £29.97 as per the already posted deal.
I bought of them one, apart from lacking in bass the sound quality is very good, tried it with my 4th gen iPod Touch and it worked, both charging and playing from it. However it is a pain usability wise, requiring a couple of button presses to do anything except adjust the volume in radio mode and the display is a bit small and hard to read.
However it is a very nice little unit, quite compact and runs off 4 'AA' batteries as well as mains, not perfect but excellent for £15 :)
