its probably a cyclical thing like when survival aids and all the survival schools went out of business in the late 80's when we were less likely to be nuked except via playstation or pc games.
competition from dedicated online retailers, every shop in the highstreet offering bushcraft style items and ebay cant help as its not so easy to maintain margins compared to impulse shop purchases, if all they did was run a shop then I might be concerned for them but it is strange that they closed down a healthy online shop run from scotland to relocate it and open the london store then close the online bit a year or so later.
