Regional deal, but Disney Infinity is BOGO 50% off for figures and playsets at Meijer, and they are also doing a 15% off GM on Friday and Saturday. So it's potentially 65% off one figure. Not quite B1G1 free, but for someone like myself who is still working on building up their collection, it might be worth checking out.
EDIT: Thanks for the people who helped me out with the figure info. I went ahead and got the 360 version as well, and as far as I can tell, ownership just means that I have to keep taking ownership for each system, and it saves my level on the profile instead of just on the figure. Really wish I had gotten into this sooner, it's actually really fun.
