Arn't Kentmere films owned or produced by Ilford also?
Freestyle has most of them in stock. Prices are less than they charge for Ilford
B&H lists them also, and for lower prices, but seems to be out of stock quite a bit and that renders their lower price meaningless. B&H regular prices on Ilford are about 15% lower than Freestyle but at least they mostly have Ilford in stock.
B&W Film just seems to be on an inexorable march to higher prices, increasing even faster than general inflation. Of course old farts like me remember buying 100 ft. roll of Tri-X for less than $10 in the early 70's In fact I could walk into Altmans in Chicago and buy a bulk roll and a box of 10 Kodak snap-caps for $10 with change left over.
Now a single roll of TX, 35mm 36exp is getting closer to that price.
