Kobo knows… Winter is Here, and because long, dark nights are great for binge-reading, Kobo is offering 40 percent off select box sets through Nov. 18th. Use the code NOVSALE to snag the Trouble Wears Tartan trilogy for $2.99. (Links here for US, UK, Canada, NZ, and Aus Kobo stores.) If you don’t have a Kobo e-reader, you can download the Kobo app to your device here. The listed price will show up as $4.99, but apply the promo code at checkout, and save a bundle.
