There's always customs fees when it comes to ordering stuff from their store.
However, there's no customs fees on top of the price that they list there, unless you're buying stuff off their store.
(Well, not sure about the freebie. I assume customs duties are included on it in the membership price, but not 100% sure. It would be stupid otherwise though)
I didn't get a custom fee when I received Dion, so I think it's when you order something then you will get a fee.

If in the next 2 years they have X-Brawn and Prowl as incentive figures, I may actually join up. Side Burn alone really isn't going to convince me, unfortunately not even with the reduced price.
