Upon joining, some developers are being sent emails that “as a token of their appreication” for joining, Amazon is waving the program fee for the first year of participation in its App Store program.
It is not known whether this applies to all developers, for early adopters or people chosen at random. It might give that extra incentive for those developing apps for the Android Market that may wish to make some cash on the side which is exactly what Amazon are hoping.
Here’s the email in full:
We are pleased you joined the Amazon App Store program and as a token of our appreciation, you will not be required to pay the $99 program fee for your first year of participation in Amazon’s App Store program. Program fees for subsequent years will be due on the anniversary of the date you accepted the App Store Distribution Agreement.
