As a seller, why do you feel a need to micromanage deliveries?

As a buyer, why do you consider AP delivery times to be relevant to selling?

I sell half my items as large letters, untracked. The other half go as parcels. I have no idea what tracked items show as delivered, nor do I care.

I certainly wouldn't spend any time on micromanaging things out of my control.

Maybe your complaint is more about YOUR OCD, rather than real life.
