I was wondering how sellers handle paper as it ages. Generally paper doesn't have an expiration date like film. Is there any manufacturer or distributor standard for how long a paper can be sold as new? And if paper is removed from seller's shelves as it ages out what happens to it? I've seen expired film being sold. It's listed as expired and has a price reduction. Never have seen paper sold this way. I've seen some very cheap paper prices online and it's got me thinking.
