I have registered my (free) Apple developer account years ago and long before AppStore started. Now I upgraded to a paid account and want to provide in-app purchases for my apps.
I don't find an option to set my apps to a price, except than "free". I have searched the internet and know that I have to sign some form but I can't find that form or any link to provide the required information to update an existing form.
Has anybody an idea where I can look?
