Well Freestyle Does sell it.
Also I did a Google Shopping search and found that even Staples and Quill now sell Kentmere Paper!
Don't also forget about the downward spiral of a product. It does not sell well, fewer retailers then carry it in stock, it sells even less then, since it brings in less money the maker of the product does not have the money to advertize it, etc.
I will be sad to see it go. However if it will last 5 years in storage perhaps there could be a special run every few years like the ULF order. Only Harman knows what the sales were and if this can be done.
