Sad they are closing but then I'm not surprised.
Many of you have mentioned the reasons that I don't shop there. They are too expensive, they feel like an outdoor fashion store with staff who are not outdoors people themselves, they are often competing against each other with a Blacks and a Millets in the same high street.
I think that it may be true to some extent that shops like Argos, Tesco and Asda, and now Halfords as well, are taking some of their business. Before Millets was about the only high street chain that sold camping gear. Casual campers who just want a cheap tent they don't have to bother bringing home after a festival or couple of nights out somewhere can just pick one up at a retail park or supermarket now.
The local outdoor store where I live recently closed down, even their bargain prices were too high for me. All I bought from their closing down sale was some Nikwax Down Wash (and that was full price

). Someone opened a cheap and cheerful outdoor shop just a few hundred yards away, although he is aiming at a different market (bargain hunters) he probably took away some of their customers.
Even though it was a privately owned store it still had young snooty female assistants so you couldn't go there to get expert advice on which kit was best. It reminded me of Blacks a lot.
I guess I'd better check out my local(ish) Blacks and see if there are bargains to be had. I somehow doubt it.
