They became available just before Christmas at Toysrus. I have seen them in all the stores noted by the PP as well as the Lego store in Tigard, OR. They may be more in demand in DTD....
Oh, I knew they were in local stores .... but as a souvenir and such, it would be a good one. We don't buy toys except holidays...& DL trips. Plus it would give him something to do on the long ride home!
