this is what i get when I try to relist
You have to have a credit card linked to your paypal account as a back up method. They will still take the money from your paypal if there is enough money in it. but if not, they will charge your credit card.
It is perfectly normal and that is how they operate. They will let you sell for some time without having this back up method, but at some point, they will require you to add it if you want to continue selling.
