Don't know if anyone else's DCs have been interested in this (it's the only thing from aaaall the adverts that DD has been drooling over) but I searched it on amazon this morning, and it came up as just under £30 from a marketplace seller.
But I went on the 'new and used offers' and it was listed, new, at £14.99, sold by amazon. It's a 'dispatched in 2-4 weeks' thing but I'm not fussed as it's for Xmas and will still have plenty of time to return it if it's crap or wrong or something.
No idea how long this low price will last but thought I'd give a heads up in case anyone else was interested.
