I was stocking up on the Verbatim blank DVD disks offer (posted on this site a couple of days ago) when I saw this Seagate PORTABLE 2.5 inch hard drive at under £40 (a tenner less than Amazon and loads less than Play) - usually comparatively more expensive than desktop sized ones per GB. Six left in the Sainsburys in Lincoln, next to the MP3 players, presumed a nationwide deal at half price. Insufficient capacity for some people but a handy size and maybe enough space for others. Not online.
