What do bookstores, etc. do with calendars from the past year that didn't sell?
You can't use them (well, you can use them for art, as Sherry and John mentioned), you can't sell them... do they go in the dumpster? Get recycled? Given away for free to anyone who'll take them? Ok, that last one is wishful thinking...
I'm totally going to ask someone next time I'm in Barnes & Noble.
But until then, any ideas? Have you worked at a calendar company/bookstore and know what happens to them? Do tell!
