Seibertron has American pricing for the sets up: USA Platinum Pack Pricing

Looking at the prices of the two I'm personally interested in:

Brakeout pack: $69.99 USD
United pack: $129.99 USD

Given that these are exclusive to Myers in Australia, I can see them being double the price here....in which case I would either import or pass all together. I do hope I'm wrong with my guess.
