A couple of collections of non-fiction titles are part of Kobo's 60% off sale good through Jan 8. These are already on sale at $2.99, and then the 60% code stacks on top, to make them $1.20 each, and if you have the Kobo VIP thing, then that also stacks, and they are even a little less. The coupon code for the sale is OPEN60.
The American Experiment by James MacGregor Burns contains
The Vineyard of Liberty,

There are a few other of these "already-on-sale-with-stackable-coupon" titles that turn out to be pretty good prices, if you just take the Non-Fiction part of the sale, and sort by ascending price. Here's a link for that too:
