A bunch of recent price drops at Kindle US on titles in Donna Leon's excellent IMO Commissario Brunetti series, to prices ranging from $2.99 to $3.99 each. There are also a number of titles that have been at $1.99 to $3.99 for a while, so I've done the link to pick up the $1.99 ones as well.
Right now sixteen titles are at these prices, so if you want to fill in some gaps, this is a good time to take a look...I was able to fill in the single remaining title I needed, other than the most recent title, which has yet to go on sale.
