I was at LEGOLAND California this weekend and lo' and behold at the Big Shop, they were offering the Kiss Kiss Tuxedo Batman keychain polybag set for free with purchase. The signage said $75 in The LEGO Batman Movie sets were required to qualify, but at the counter the nice gentleman clarified that the threshold was just $55. Offer is good while supplies last, obviously. One other noteworthy thing to mention about that was a 10% discount on all purchases made before 12:00pm which I wasn't aware that they offered before. It, unfortunately, does not stack with the passholder discount but for those of you in the area, this might be a nice way to get the keychain without being subjected to aftermarket prices. I am unsure if this deal is offered at other LEGOLAND parks or Discovery Centers, but it's worth a phone call to find out.
