Took a little over a week to get a bat last week. Was showing shipped and at a 2nd facility with no updates for days. Finally showed.
That said, I had shipping info to be able to see that so I wasn't too worried. If you sell something, and don't communicate the follow-up, that is bs. Personally, if you can't do it you should wait til a time you can to do your dealings. If you are going to be gone, still can leave the buyer hanging but if absence comm'd prior isn't quite as bad.
Limbo is just not a fun place to be for anybody. Just don't put that on peeps.
