I'd just like to inform everyone that use by dates don't matter with POGO paper. Polaroid have to put a use by date on it because of the EU as it's considered a consumable. The paper will in fact last forever provided you keep it in the right conditions (temperature, humidity, etc). The crystals in the paper will remain perfect regardless of use by dates until you print a picture, thus heating the crystals up to produce the image. So the paper is absolutely fine. Also, this 90 pack offers the best value for money you can get for the paper. It's actually 3 packs of 30.
