Oh ya, sorry i misunderstood you.
We can get the localized through the loadProducts, and are using on some apps. Although localized price are fine if you are using them only to display them to the user, we need to download the price of items to make internal analytics and use them to measure how much each user is spending.
We currently do this in iOS, and this information would allow us to do the same in Android. It should be a small enough change, seeing as this is already provided through the IabHelper class that Corona seems to be using. If this feature could be moved up the priority list it would help us a lot.
