This may very well be 'old news' to many but earlier today I was visiting the Frankfurt Christmas Market in Birmingham and on the way back to the car I called in to WHSmiths. The Birmingham store now has a ModelZone section selling a limited collection of both plastic construction kits, diecast cars and model making books.
I checked the internet and it appears that WHSmiths have bought the ModelZone name and will be selling plastic kits under the ModelZone name and in dedicated model making areas in their larger stores.
For more details see this link.
Look out for special offer vouchers giving 20% off throughout the ModelZone store (valid until 8th of December 2013).
