In fact, I think I’ve worked it out. If you click on the profile button in the top right-hand corner of your Paypal then there will be a profile and settings option. Click this, and it will take you to a page where there is a menu on the left hand side. Click the tab ‘my selling preferences’ and you’re good to go!

I can’t work out how to do it with the new Paypal site either. Have you had any luck?
