I went into the computer store Game today, just to see if they had the Tron Disney Infinity figures in stock.
And they did, both the Sam and Quorra ones. Although I don't actually have Infinity at home (or indeed any games console at all), and despite the slight cartoon like design of the characters I think they're actually pretty okay has collectable display-on-your-shelf merchandise goes.
The price seems reasonable enough (14.99 each), but money's a little tight at the moment, so I might
wait unitl my next pay day before thinking about buying them.
