What currency does the Google Play Store display in? So, according to the help desk (on Google), it says the following:

Note: You'll always see the currency you'll be charged in before you complete the transaction.

The only problem... Is, that I'm not seeing any currency changes. No prefixes (ie. A$##.##, S$##.## or U$##.##; for Australian Dollar, Singaporean Dollar or US Dollar) or anything.
I've found instances where people are seeing two different currencies; one before purchase and another after the purchase (in their current country's currency).
For example (Before purchase screen):

(Confirm purchase screen)


For me, it however... It does not change, so - I have no clue which currency it is actually showing prices in.
(Before purchase screen)

(Confirm purchase screen)

As for through an actual Android device, it only displays the amount and not the currency.

tl;dr - The question is:
Looking at all these pictures, will I be charged:

$2.33AUD? (Currency of credit card)
$2.33USD? (Assumption that Google is using its own currency)
$2.33SGD? (Currency of location; where I am)

Also, as usual - The above costs does not include processing/conversion fees and charges, and other stuffs and whatnot that goes behind the scenes that ends up getting lumped onto your bill.
Okay now I just checked the same app here as you can see:



So it shows the price in my local currency.

I also checked that 4.78 TL is equal to 2.33 AUD, so that price you see there is in AUD.
