I just noticed that the analytics which track purchases don't seem to be converting currencies correctly or at all. Everything seems to be reported as unconverted USD regardless of whether the purchase was made with a different currency.
For example we recently had a transaction made with RUB (this is Russian Rubles I believe). The value in RUB is about 282 and the item purchased is a 4.99 USD item. The analytics are showing it as a 282 USD purchase. Makes our monetization look much healthier than it is.
