FYI, BBTS has these up as well, so they aren't exclusive to EE in any way.
Of course, BBTS has the set, but it's at the same price as EE's singles, so you really only save on shipping. While I like this idea, and I'd like to have a set, none of these figures justifies $10 each. I have the SDCC sheldon, and he wasn't painted as much as dipped in a bucket of paint with the consistency of pancake batter.
