I guess Kobo will be left wondering why their sales drop a lot in some countries
Fingers crossed they'll still give out the occasional 60% - 80% one-time use coupon codes that were good in multiple countries like in the old days.
It doesn't matter how many coupon codes you win here in the US if they still don't allow them on agency books. I do buy from other publishers but a lot of my autobuy authors still write for Penguin and its various imprints.
