Robot Martini has this game for $25 normally. Its holiday price is $5 off.
However, Empire Board Games has it for $13.05 + 5.80 shipping, at a total of 18.85. While that's not a GREAT deal, it's still the best I've seen, and this is a simple, accessible, charming game.
It's also pretty small, so if you take advantage of one of Empire's other low price offers, you might be able to spread out the shipping cost a little.
The game was delivered to me inside of a week. Pretty speedy.
