Some kids/YA sale titles for $1.99, couponable at Kobo, prices good for multiple stores in Canada & US (may possibly be available in other regions as well).
Open Road Media are holding a Teen Read Week sale until Oct 18th on the following titles
on their announcement page. There's a bit of overlap with their other promo ongoing until Oct 31st in
gweeks' dedicated thread for all their Halloween-themed sale stuff, so you can pick up additional books by selected authors (there's some old school kidlit classics names like Lois Duncan and Zilpha Keatley Snyder).
