Through December 4th, Kobo CA, UK, and US are having a rather nice weekend sale on Chilly Thrillers, which in some cases includes Horror and SFnal ones, under £2.99/$4.99 CAD. Most are priced under £1.99/$2.99, with a substantial number at the £0.99/$1.99 mark. Some of the prices are just current publisher markdowns being spotlighted, but some of the things from the smaller presses are Kobo-exclusive markdowns and usually couponable/VIP discount-eligible.
The selection is actually pretty good, with a mix of stuff from large (the many divisions of Macmillan & Hachette) and small publishers (Head of Zeus, Orenda, House of Anansi, and other specialty), with a few indies thrown in, and a generous selection of translated works if you're into international authors, and many well-known authors and/or awards-recognized series in the lot. A fair chunk of my wishlist is in this.
In Canada,

I should probably note that this being Kobo, some of the titles and authors aren't filed in the categories one might expect. Quite a number of foreign-language authors are filed outside of the dedicated International Mysteries and Nordic Noir cats, and some non-Nordics/domestics in, so it's probably worth making a trawl through the adjacent categories of whatever you're regularly interested in as well.
Semi-related to that, Quentin Bates and Michael Ridpath are English authors writing series set in Iceland—I really enjoyed Ridpath's Fire & Ice series, for which the
1st has been a freebie and the later novels not available as e-books in North America were on my wishlist (I read them in paper from the library and have been waiting literally years for them to pricedrop), and Bates' series was also pretty decent. ETA: I should probably also note that Bates'
Frozen Out (in the UK sale) was published in North America as
Frozen Assets, and has been a $1.99 Soho Crime bargain a few times in the past which you might already have, in case you travel. Also, the handful of tie-in novellas by Bates and Ridpath are both at what IIRC are regular prices, so you can wait to pick them up later.
I would recommend them both without hesitation for readers interested in trying faux-Scandicrime (especially if you happen to be a Tolkien fan, since the 1st-in-series Ridpath novel has a reasonably substantial connection to his works in the plot).
