Anyway, we bought a couple more boxes in an effort to get the Millenium Falcon and the X-Wing fighter. We managed to get one in.
The other 2 unique toys are Chewbacca's Wookie Gunship and C3PO on a Tantive IV.
I'm a bit disappointed with C3PO, actually. On the mini poster, Threepio had a shiny, metallic finish. It's not the case with the actual toy.
The other 3 eggs revealed duplicates.
We still have that elusive Millenium Falcon to hunt down. But would we want to purchase more eggs? Only time will tell.
