My current code checks the country code and then changes the drop down value before submitting it for the things to refresh in right currency pricing, but I've tried things like, putting return; to stop it after running it once and moving return; on different line with no luck. I even combined the .val line with .change() thinking maybe having it on separate lines was running it multiple times and refreshing it multiple times.

Here is my code;

$.ajax({
  url: "https://ipinfo.io/json",
  type: "GET",
  success: function(location) {


    if (location.country === 'AU') {
     $(".shopify-currency-form select").val("AUD").change();
} else if (location.country === 'AR') {
     $(".shopify-currency-form select").val("ARS");
} else if (location.country === 'CA') {
   $(".shopify-currency-form select").val("CAD");
} else if (location.country === 'US') {
   $(".shopify-currency-form select").val("USD").change();
}
return;
}
} );

$('.shopify-currency-form select').on('change', function() {
$(this)
    .parents('form')
    .submit();
return;
});
