They are owned by the infamous Gold Brothers they have an identical site here: Scotlandshopdirect.com

I don't know what you are actually looking to buy from them, but much of what they sell is cr*p. Also they do very little to support traditional Scottish weaving and industry. I wouldn't buy a postcard from them.

Of course this is my opinion, you will find others with stronger ones.

There are many reputable kiltmakers on this forum. I don't know what your budget is but whether a casual kilt or a hand-made one you will do better here than with Gold Brothers.
