PayPal payments can be selected as "service" or "friends and family" with the former resulting in the Club paying fees. Whilst we cannot encourage members to pay using "friends and family" we can't control what people do.
International payment via IBAN should be possible, but there may be fees that you as the sender have to pay. I use a service called Wise which charges lower fees than PayPal, and here's a referral code if you are interested:
