Just a quick heads-up and a plug for a great photo shop in the Boston area. Newtonville Camera has a couple of boxes of Tech Pan film in 4x5 (exp. but should be good) at half price along with a pretty good pile of slightly (some a bit more than slightly) out of date Kodak paper at half price as well.
These folks are great people and their Ilford supplies are kept up to date and extensive. Lots of postcard paper, for example. If you're in the area, especially if you are bereft due to the demise of Technical Pan film, give them a try.
Truth in advertising: I get nothing for this plug except the joy of seeing a good shop stay afloat.
