These were just released yesterday at Denny's. I'm not sure how long the promotion will be going on but here is what I know so far (all info courtesy of the thread on the Promotional Card FB page):
-$3/pack (2 cards/1 coupon) with a limit of 4 packs per visit. -12 card base set with puzzle backs (forms two puzzles, one of the Falcon and the other of a TIE fighter). -There is a foil parallel of the set. Odds are unknown at this time. -There are also collector cups that have a Millennium Falcon lid. -Sales benefit No Kid Hungry.
