I haven't seen it anyplace but TRU. But, then again I'm usually the last place to spot anything new coming out. I haven't even seen the POC TRU exclusives yet.
I think they will show up eventually. I've seen snowspeeders, twin pod cloud cars, and vintage ESB figures at Target. It's just a matter of time. I hope Walmart has them for a ridiculous price so that they will have to clearance them after X-mas.
