I also see that they have a Melissa & Doug Wooden Railway Set for 49% off.
I'm always looking for early birthday/Christmas ideas, so I'll post the link to these weekly in case anyone else is looking also.
One other item I want to mention that is on a hot sale right now at Amazon is their HDTV's are also on sale, along with other electronics. They also are offering free scheduled delivery to any room in your home on every flat-panel HDTV 40 inches or larger. If you've been thinking about getting a new TV, check out some of their specials.
Enjoy!
