Where to buy a USB Mains charger for an MP3??

Question

I desperately need a USB mains charger to chrge my mp3 when i go on hols on sunday (its the one which is basically a plug with a usb port on the end to allow u to charge it via the mains). it cant be an online shop...i just cant think of a store i could go to to buy one?

Any suggestions would be fab (UK stores only...i looked at Maplins, Argos, Dixons etc but they either have just an ipod one or they are too expensive i.e.£15!!)

cheers guys
