I could be wrong but I was under the impression that when you order from Digital Truth many (but not necessary all) of your items actually ship from Freestyle. Why else would they sell Legacy Pro items for the same price as Freestyle?
I bought some Varycon paper from DT earlier this year & it arrived in a Freestyle box with a Freestyle packing slip. Postage was cheaper than if I had bought direct from Freestyle! I assumed that DT was some kind of re-seller.
Hopefully with the Slavich they are stocking it as it would be frustrating to lose access to an interesting emulsion.
