I don't know how much to trust the Amazon listings at the moment.

The move to integrate Comixology with Amazon Digital Comics seems to have cause chaos to the system as a whole, with Digital Comic sales currently only available on Amazon US and UK stores, but no access to Comixology for international readers, a shift in which media they then want to promote as the primary one - the digital one or the physical media.

Comixology should have been kept online for another year while they worked this all out in the background. Instead a rushed a problematic rollout has dropped digital sales from between 20 - 70% (https://bleedingcool.com/comics/comi...-huge-amounts/)
