What happens to magazines on newsstands that aren't sold?

Question

What do grocery stores and book stores do with all the magazines they don't sell for that month? Is there anyway to get these old magazines for free once they go off newsstands and are replaced by the new month's issue?

Answer 1

My best guess is the covers are stripped and sent back to the publisher and the actual magazine is thrown away. I worked at a book store and that's what we did. A little sad I know.
