Thanks for the offer.
At the moment, I'm just holding off purchasing any series 2 discs until I can gather some more information on this power disc set.
I'm not really finding anything at the moment.
But I'm hoping in the future when the exclusive deal ends, they'll start selling it in the retailers I have access to and I will be able to obtain it for the actual retail price instead of what ebay sellers were asking.
For example, if I was to buy two of them at ebay prices, I'd be paying $200!
In theory, if I was to buy them instore, I think it would be $100.
As an aside, I wonder if Elsa had any interactions with Rapunzel in the Frozen movie?
We see Anna greet her directly, but I don't know if Elsa met her.
When I can see the movie (release date 26/12/2013 here), I'll keep an eye on that scene (and any others) to see if Elsa does meet Rapunzel.
