Could you say what is the production status of Ilford PAN 100 and 400, please? Have they been discontinued? There isn't any information about these films on your website.
A couple of suggestions for your consideration:
If this Kentmere paper can't be produced continuously, how about adding it to the annual ULF run? Tell people what is the minimum order for a production run, and lets see what is the response! Advertise on your website and let people know.
I can't figure out why a film made in the UK sells for a higher price than one made elsewhere. I'm talking specifically about Kentmere films. Until last year they were sold at competitive prices at the retail point and about the same as other films of same quality from the continent. Then the retail price jumped to about £1 more per roll, where others had a smaller price increase.
Could I suggest doing some form of seasonal discount for these films? I would love to buy "local produce", but with prices higher than the competition, I can't afford it!
I've never even heard of Ilford Pan 100 or 400... weird...
