Greeting Card Mystery Bags include a random mix of 10 of our (amazing and hilarious) greeting cards and 10 plain white envelopes for $30 (that's just $3.00/card)! The contents will differ from one bag to a next and none of the bags will have repeats! Though rest assured, we're not jerks (well, we kind of are)... so we won't be filling a bag with 10 Retirement cards (or something equally silly).
