There's a whole bunch of new sets on their website.
While I agree with Ras that the inclusion of a horse (I have hundreds) or small rowing boat (I have dozens) decreases the value of the blisters for me, they're a good way to get extra horse/boats if you don't already have them, and better value than the carry cases.
Tim mentioned to me a couple of days ago that a new green dragon was coming, and he appears in a set with a a cut-down tower from the Dragon realm for $30. I'll have to get at least one of those.
Knowign how limited our TRU shelves are locally, I'm wondering which of these new sets will appear there at all, and which I might have to order online.
