I have three educational games by ThinkFun that my kids have played and grown out of.
* Gravity Maze ($15): In really good shape, but a small nick on the box.

* Laser Maze ($20): This one is like new.

* Laser Chess ($15): The box on this one is a little beat up, but the components are all in good shape.

I can sell all three for $40. I can meet in the Lynnwood area or deliver within about a 10 mile radius.
