Done a bit of snooping. The PO Box address is registered in Spalding (just down the road from me oddly enough). The website is hosted by a company in Derbyshire who have several links to the site and 2 testimonials (one owner, and one customer), and the payment mechanism is with PayPal - I know for a fact you have to be scrutinised for a PayPal business account. I haven't called the mobile number, but I emailed to ask for some background. The owner said he's a small startup business just trying to supply folk with gear 'at the right price'. He has only had five customers since starting last week, and I mentioned the comments made here and he seemed reasonably hurt, but not surprised that small businesses fail so easily.
So I thought '**** it' and ordered a jacket and trousers - so it'll be me tahts stung - or not as the case maybe - i'll keep you posted, but he might be for real, ever thought of that?
