The labels function seems like a good idea on the surface but I am wondering why I MUST pick a "special service" for all mail classes? I thought I would try it out and found my 1 ounce letter was going to cost 44¢ for the stamp and like $3.00 for Certified Mail. I don't want to certify it but I have to pick some extra service. It looks like that is the same for other mail classes also.
I certainly won't use it if I am forced to pay for services I do not wish to use. Maybe I am doing something wrong?
