Amazon removes $20 in-app purchases limit

Amazon recently sent out an email to developers stating, “With our parental controls functionality now updated, in-app items over $20 may now be submitted via the developer portal.”
Considering that one study found that purchases over $20 account for 51% of generated revenue, it makes sense that Amazon needed to lift this ceiling in order to attract and retain serious developers and continue to position itself as a serious contender in the app store space.
