Just off the main drag through Stafford town centre is Salter Street Toys and Modes - in Salter Street as it happens.
While a general toy shop, and not a huge one at that, the range is decent enough. Some Bachamnn, Hornby, LGB, plastic kits, balsa aircraft,Humbrol paint and a smattering of oddball specialist items. Basically, something for everyone but don't expect a big-time specialist.
Watch your head as you walk in - the ceiling in this old building is all over the place - but well worth dropping in when you are around.
No specific website, but there is this on the Stafford Town Centre website
