When listing an item, the postage section allows you choose what postal service you will be using, in your postage policy. For example, because I have always sent with 2nd Class Standard, I choose that.
However, underneath this section it states 'Simple Delivery will override your postage policy' - as if to say it's pointless what you choose, we're going to override it with our label anyway.
It seems to be that Tracked 48 is the default label I am getting from SD, so what is the point behind choosing a service at point of listing if you SD is going to give its label of choice anyway?
