Where did you pre-order?

GameStop

Got the starter pack at Gamestop and taking Mike or Dash as my free figure, then buying the Villains 3 pack.

Amazon.com

I went through GameStop. And here is what I preordered...
Starter Pack for Xbox
Free Figure (Violet)
Free Power Disc Pack (Came with Reservation)
Lone Ranger Playset
Cars Playset
Sidekick Pack
Villains Pack
Dash
Mater
Francesco

I think that is pretty much everything! And on launch day I will head to Toys R Us and buy 4 or 5 power disc packs and if they have the exclusive Lightning McQueen I have heard of I will buy that and maybe return my Cars Playset back to GameStop...

GameStop

Ordered the starter pack from Toys R Us
Ordered 3 packs of power discs, Prima guide and infinite possibilities book from Amazon
Planning to get the bag and power disc album from Asda. Unless the Toys R Us exclusives are available in the Uk in which case I'll go there.

Not a lot of preorder bonuses in Norway, but I ordered from cdon.com and got Peter Pan Hooks ship disc.

EB Games:
Disney Infinity Starter Pack
Cars Playset
The Lone Ranger Playset
Sidekick 3-Pack
Violet
Mater
Francesco

The only figure I didn't pre-order from EB Games was Dash. They didn't let me choose which figure to get for free and said I can choose the figure I want depending on what they have available on the release day. I really hope Dash will be available so I don't end up with a figure I already have.

Toys R Us:
Villains 3-Pack

I pre-ordered the Villains 3-Pack from Toys R Us since EB Games said they never had the Villains 3-Pack available to pre-order.
