Some couponable sale books now that Kobo is offering a 50% off unlimited use code this weekend-ish, valid in Canada & the US and possibly elsewhere (likely matched at other retailers as well, minus the couponage):

Sourcebooks has a handful of markdowns from $1.99-$2.99: linkage for the lot. Interesting-looking titles include:

• Eatymology: The Dictionary of Modern Gastronomy which gives origins behind and trivia about a number of foodie neologisms.
• Heist: The Oddball Crew Behind the $17 Million Loomis Fargo Theft, quirky true crime about Exactly What It Says In The Title

Houghton Mifflin Harcourt are apparently no longer couponable in the US, but can still be discounted in Canada. They've a number of sports figure biographies, nature and history titles, cookbooks and other non-fiction at the $3.99 CAD mark (plus some literary and historical fiction and about a page of $2.99 tween/YA novels starting before that), starting on page 6 of their listings and going up to page 12. Interesting-looking highlights:

• Deep Blue Home: An Intimate Ecology of Our Wild Ocean
• Nature Noir: A Park Ranger's Patrol in the Sierra
• Chocolate: Sweet Science & Dark Secrets of the World's Favorite Treat
• The Mantle of Command: FDR at War, 1941–1942 (blurb says this was longlisted for the National Book Award)

Algonquin only has a couple of non-fiction titles at the $1.99 mark, and a few more literary fiction: linkage for the lot. There's a nice-looking history/facts/trivia illustrated travel guidebook: Very Washington DC: A Celebration of the History and Culture of America's Capital City

Steerforth Press (who have some child imprints that do very nice foreign-language modern literature translations) has only two non-fiction titles at $1.99, but their books are generally good quality, in my admittedly limited experience:

• The Essential Guide to Being Hungarian: 50 Facts and Facets of Nationhood (this is composed of topical articles which provide a cultural overview from a humorous perspective outside the regular guidebook sort, and I bought this myself to go with the previous sale one in the series on Polishness, which I liked)
• A Criminal and an Irishman: The Inside Story of the Boston Mob-IRA Connection

Chronicle has its usual selection of cookbooks, as well as some parenting guides, at the $1.99-$3.99 mark: linkage for the lot (some of them are short pamphlet types which are that price regularly, so you may need to check the size of the preview/page count)

Workman has a few crafts and self-help books @ $1.99: linkage for the lot (if in the US, you may see a number of regularly-priced cookbook shorts as well)

ETA: Oxford University Press has two titles at the $2.99 mark:

• Chop Suey: A Cultural History of Chinese Food in the United States (actually two listings for this, and I can't tell the difference since they're the same ISBN and format)
• Feeling Unreal: Depersonalization Disorder and the Loss of the Self (looks more clinical psychology than self-help, but with some advice)

Skyhorse Publishing has a number of titles for $1.99 (mostly cookbooks & fitness, but with some history/biography: linkage for the lot. Their Arcade imprint also has some $4.99 discounted titles which are additionally couponable: linkage for the lot. Most interesting-looking titles:

• The Golden Warrior: The Life and Legend of Lawrence of Arabia by historian Lawrence James (Wikipedia), a 2008 updated version of his 1990 biography.
• The True History of the Elephant Man: The Definitive Account of the Tragic and Extraordinary Life of Joseph Carey Merrick
• Ingmar Bergman: An Artist's Journey, essays about the legendary Swedish film director
• Buon Appetito, Your Holiness: The Secrets of the Papal Table (a history of foods served to popes over the centuries and their dining habits)

Random House's occasionally-couponable Vintage Digital imprint offers the following @ $4.99 (seems to be a glitchy regular price rather than a markdown):

• Greek Science After Aristotle by Dr. G. E. R. Lloyd (Wikipedia) a Senior Scholar at the University of Cambridge
• Early Greek Science: Thales to Aristotle is available for $7.99 CAD which is not particularly cheap, but should be couponable if you want the set.
