I think I spent mine on the Time Travel series western wear... not sure at the moment what I spent it on.  I think I had a penny left over when I was done, lol.

The dinosaurs they're promoting now look interesting, but all the "famous" species were in the P6 Volume 1 set.  Now they're down to the species that your average gradeschooler couldn't identify.  :P  They're decently priced with the passport discount though.
