There are a lot of different words we like to use in connection with deals that cost nothing: free, nada, zilch, and (our very own favorite) bupkis. But no matter what language of gratis you speak, these five Editors' Choice deals — including a yearlong magazine subscription, a zombie apocalypse class, and admission to museums on September 28 — won't set you back a cent.
