Guys, I just happened to check my cart at Barnes & Noble, and right now they have some of the "___ Warships in the Age of Sail" series (these are the "bibles" Ares uses to build Sails) on pretty nice markdown.
French Warships in the Age of Sail 1786-1862: list $76.95, now $47.50
Russian Warships in the Age of Sail 1696-1860: list $85, hardcover $52.73 or NOOK digital edition $53
Dutch Warships in the Age of Sail 1600-1714: list $78.95, now $48.73
The BWAS Trilogy that started it all are still stupid-expensive at $100/copy, though, and they don't even offer the Nook edition on 1714-1792 that I bought.

Also, coupon code BNWILD gets you an extra 20% off one (not digital-copy) item--admittedly, it's 20% from the previous price reduction, but it's still enough to knock off a nice bit of cheddar. :) (I paid $38 plus sales tax on FWAS, about $42 final cost, and leveraged my mother's BN membership to get free express shipping.)
