I was in Modells sporting goods store yesterday(across from the Barclays Center) picking something up.
They had a box of 20% off vouchers for the NYC-42nd Street location. The vouchers expire on 12/1/14. Note that it is 20% off the All Access Pass and it can not be used for advance purchase. 20% off each adult and child purchase. Must be presented at time of purchase. (I copied most of that right off of the voucher.) It doesn't look like there are any restrictions..except the All Access Pass needs to be purchased. (I don't know what the cost of an All Access Pass is.)
I grabbed 6........so if anyone will be in NYC before 12/1/14 and is planning to visit Madame Tussauds, I will be more than happy to mail it to your hotel/home. Just send me a PM and I will fwd. You can have all 6 or any combo. No charge of course.
Note....I have no affiliation with Madame Tussauds. As a matter of fact, in all of my travels all over the world..I have never even been to a Madame Tussauds.....
