how long do YOU wait

You could always start a “waiting to ship” shelf like I have, to remind you about people not to deal with. Some parts on my shelf have been there for a couple years, all packed and ready to ship. Good thing I don’t need the $$, or I would go back, open the boxes, retake the pics and re-list the items again, and start the whole process over. And yes, there are some very prominent members who have a box there!
