Just thought I'd recommend online retailer http://www.gundoggear.co.uk
I ordered a couple of bits off them just after new year (they do other stuff aside from doggy products), as I found the prices we're competitive and they do a BASC discount as well.
A small blip with my order (out of stock) was sorted out very quickly and the few emails back and forth were replied to in a fast, helpful and personal manner (even outside business hours). They obviously value their customers and do what they need to when it comes to looking after them.
No affiliation, etc, etc. I just thought I'd give credit where it's due!
