I have it. It used to be avaiable only from Amazon or that site you link to above. It is going to be available in big chain stores in the US soon.

It's low-budget and campy, and purposely aimed at little ones more so than their videos are. The script is pretty lame, but Ryan and Sean (and another youtube star WHATTHEBUCKSHOW) are all pretty engaging in it. It's a foot-in-the-door for them, and a keepsake for fans. I enjoyed the behind the scenes bonus track the best.

This is the youtube video with the trailer and a special intro by Ryan and the "new Sean":

And this is the announcement about the premiere in a few select theaters:
