I got a $25 Amazon gift card for Christmas from my brother-in-law. I know this isn't literary or even inside your 2 dollar range, but I got one of these: 6 Cup Bialetti Stovetop Espresso Maker. If you like coffee, this is the best espresso I've had that wasn't from a high dollar machine.
I received one of the same amount for Christmas & and was able to pick up a copy of Bavinck's abridged Reformed Dogmatics by adding less than $2 change.
