I have fives for most of the criteria, but only 4.9 for posting. 

I post the day the buyer pays, unless they pay after 4.30, and I assume the markdown is because the buyers are not all happy with the time it takes to receive the parcel.

Since I use C&S, I follow the tracking myself, and I was horrified to see that an item from Adelaide to Albany, WA, took nearly two weeks!!

I'm almost supplied that star isn't worse.
