I didn't see these posted for U.S. retail, but if it has been already, then sorry. I found the Target exclusive 3" titanium movie Prime pack today for $12.99 US at a Target in Lynnwood WA. It was the last one left on one of the toy departments endcaps. In general, with any Optimus Prime figure, I get two for one to open and one to display in box, and since I only found one these are staying in box for now.

And, in ams's Mega-Listâ„¢ (use it, folks, for it contains much knowledge), we have: I believe I read somewhere that the "Infrared" name was the early name for this pack.
