American Girl is having a great Cyber Monday sale! Up to 50% off 50 different items and an extra 10% on the last chance items. You can get a DS game for only $13, a video for only $3, and lots of doll accessories (large and small).
If you go through your UPromise account then you will get an additional 2% back, making this deal even better.
The site seems to be a little slow so you’ll have to be patient. It never timed out on me though.
