Paypal uses the currency specified by the seller for payment. By default, it converts this currency to currency your card uses. This can be a problem since PayPal does not always have a good exchange rate.
Good news is that Paypal allows you to transfer currency exchange to your card issuer.
In steps below, we will pay 15.11 USD for an item using GBP credit card attached to PayPal using card issuers conversion rate instead PayPal’s.
Remember that this change is only for current transaction. Next time PayPal will again use its own exchange rate.
On payment page, verify currency and exchange rate used by PayPal.
