@zynovo When someone signs up with us, we ask them for their currency, and we expect all events sent to our API to have only that currency.  When a store accepts multiple currencies, we need to make sure the currency we send to the event-api is the one we have registered for the site.  Magento has some baked in currency conversion, but it only seems to go one way, and we need to convert in the other direction, so we rolled our own.
