I got my set as well. If you only requested 1 set of the FSS you will likely make it out with not paying Custom fees as the Dollar amount on the Package is around $52 USD. Last round I did 2 sets and I got hit with Customs on 2 of the 6 deliveries at around $25-ish for the Duty Fees.
You got 4 Terror Dromes??? WOW! I got one and it is huge. My friends in Texas have been building the TD on the Lego Large grey base plate to make it easier to move as it prone to bow out on the bottom when being moved.
