It's a shame to see so many well known brands falling by the wayside, but as BarryW rightly says in this instance they've had their day and times have changed.
Internet shopping has moved on so much that the consumer has changed the way that we now buy day to day consumables, especially specialist products.
It is now very easy to source products from around the world, just take a look at the countries that BarryW himself buys his kits from, NZ amongst others with post & packing included in the price

. At one time you would have to order from a specialist model supplier who in turn would put on a hefty mark up on the price to make a healthy profit margin, the wonders of the internet super highway benefit the customer but affect the trader in the High Street in the long run
