Entertainment Earth is selling a case of Series 3 figures for $174.99. That comes out to $2.91/each. Which is a solid $1.08 cheaper than TRU and $0.08 cheaper than S@H. And no sales tax!

They also sell them by 3s or 10s, if you aren't wanting a whole case, but the price goes up a bit. I ordered a series one case from them. They were a little slow on shipping, as it appears they waited until the official release date.
