On their website they do say that they are internet only and that they are dealers for the "Clann Crais Collection." A little "interweb" digging turned up this site http://www.mactag.co.uk/cgi-bin/ccp5/ccp5/cp-app.cgi which is the maker fo the collection refered to. Their addy is for Glasgow, not that that means their fabric is made in Scotland, though.

(Also I believe the OP is in the UK so 199bp to him is 199bp.)
