NewEgg has the WikiReader on sale for $20. I paid $100 when I got mine 2 years ago, so this is truly a rock bottom price.
For those who don't know, the WikiReader is a pocketable custom ereader that contains an offline copy of Wikipedia. It's a fun little tool and at this price it would have made decent stocking stuffers.
And Daily Steals has a generic 8" Android tablet on sale today. It's listed at $80, but I'm not sure how good that tablet really is. It's running an older version of Android, so it wouldn't be high on my must buy list.
