The premium badge is different again. For it to show, you have to be TRS, you must offer 0-1 day handling and you must offer free postage (something is telling me there is a 4th requirement). It's been ages since I was TRS on any of my accounts and nothing has really changed. I never had a premium badge because I refuse to offer free postage and refuse to have a 1 day handling time.

Congrats on getting it! It's a chest puffing moment when it appears the first time. Go you!
