I picked up a Mamiya RB67 recently, with the HP701 polaroid back.
Where I am pack film is incredibly expensive - $30 for a pack of FP-100C 10 3.25" x 4.25" sheets. I am looking into making a big order from B&H who seem to have it relatively cheap, but I have been trying to find out how long pack film was good for if you stored it say in the freezer.

So anyone know?
