Excluding VAT, it's £114 including VAT. Worth every penny though. You have to remember that Filco is a japanese company and the UK layout is madeexclusivelyfor the keyboard company. Also, the quality is second to none (Well, perhaps with the exception of Topre keyboards + HHKB, but these start at over £200) and you can expect the keyboard to last a very, very long time.
The only "common" mechanical keyboard that I can think of that you might find in a brick and mortar shop is the Razer Blackwidow line of keyboards. However, I'd strongly recommend you avoid these if you want to actually purchase a mechanical keyboard as they are of poor quality and you're really paying for the Razer brand.
You won't find the Filco in any physical shop as the keyboard company is the only company in the UK that sells them, not to mention they are quite hard to get hold of as they are not produced in great numbers (You'll notice on the website that most of the Filco keyboards are out of stock and they tend to sell out quite fast when they do have stock)
