I just checked out the J and C web site, and I couldn't find anything here on APUG about a couple of things I "discovered" so I thought I'd note these:
First, there is a sale on defective Efke sheet film (5x7, 8x10, 7x17, and 8x20)...the perfect thing for testing, I think.
Second, I noticed that J&C are now listing T-Max 400 in 8x10 and Rollei R3 in 35mm and 120.
I hope this helps someone out there...
(BTW: I am in no way associated with J&C other than being a very satisfied customer.
