Living Social has these deals repeatedly, but most have been selling out very fast. This one is still open, and it's a great way to get some things checked off your list!
I've used them for envelope seals, tote bags, personalized stationary, bottled water labels, rehearsal dinner invites, menu cards, save the dates, RSVP envelopes, and so much more.
