Oh, yeah, going to the Advanced menu in iTunes and selecting "Deauthorize Computer" is SOOOOO hard.
Three clicks is difficult?
It doesn't work for my system and when I called to have my credit card removed they said I had to do that online. I think you missed my point. I should not have said deactivate. I mean disassociate. They won't terminate the relationship and when I try to delete the credit card it says I have to use a credit card to delete a credit card. Circular. Call them and try to get a credit card removed. They'll tell you to cancel the credit card. They seem to be designed to be intentially obtuse about killing accounts.
My wife happened to set up my kid with our debit card so we would have to cancel our bank debit card. I just gave up trying to get rid of the purchase ability and tol my kids to cease and desist (the old fashioned way). It is definitely not easy to terminate the relationship regardless of what you write.
