I saw an ad today for HT showing shirts that are now on clearance for half off, and one of the Foster's shirts was included in it. So I imagine the others are as well. I splurged a few months ago and got the "I Am Bloo" shirt, along with the grey Bloo shirt and the purple one with Bloo, Ed, and Yellow Man. I love them all.
And now you can get them for half price, so now's the time to jump if you want any of them!
