Posting this self-answered question because my friend seems to be the first to have discovered it.I live in France and have a French credit card, but the first card on my account was a US card.  The Play Store shows everything in dollars, but I want to pay in Euros.  I already deleted the old credit card from my Google Wallet and I only have my French card now, and it still shows the wrong currency.  Anyway, maybe I'm willing to pay the currency conversion fee.The main problem is that after I add my card in Google Play for android, it shows me the same screen with the price of the song/app/movie with no buy button, and when I click continue I'm just selected to choose my card again.
Google Play store continue button keeps prompting for credit card
