The developers of the Mac App Store just got another tool to promote their applications published in the store: the promotional codes thanks to which they can give away programs that normally have a price. The good news is that the codes are released directly for all countries and not just for the United States, as was the case until very recently in the iOS App Store.
The limit of code that a developer can request is fifty for each version of the application, more than enough to launch some kind of raffle or give away some licenses to interested people. In order to comply with these codes, we already have available the function to redeem them in the sidebar of the Mac App Store.
From the beginning Apple already remarked that the Mac App Store would not be the exclusive way but one more way to get programs for Mac OS X, but the novelty of being able to have these codes encourages the use of the company’s official store ignoring the fact that developers can simply send a serial number or an unlocked version of the application using other means. Cupertino will want users to make more use of the shop.
