The grand opening for the Lego store in NJ Freehold scheduled for June 21-23 has the Hulk Lego Master Builder event. Similar freebies (T-shirt $50, store set $75, minifig set $50) from other store openings will be available on those days with the purchase price indicated.
The store soft opening I've heard will be a week earlier but the freebies are only available during the grand opening dates.
I will most likely be there on Saturday June 22 in the morning.
