I found full-sized chuao/chocopod bars at my local Target. I think they were $3.99 each in the chocolate section, but they only had 3 or 4 flavors. I picked up the potato chip, honeycomb and firecracker ones and am planning to pick some more up next time I'm there. The firecracker one is surprisingly delicious!
Dang it. I was in target earlier and I didn't think to look there. Maybe next time.
