Hi samcom_hyd,
I'm sure you got this paid for already
😉 but in case someone else is looking for this answer I will post it here.
If you select the wrong payment method, you can still pay using PayPal without emailing the seller to re-invoice you.
Log into your PayPal account & select the below options.
Find the auction in your Items Won section & follow the steps.
