Completely agree that they would have me hitting the back button.

I have on some of my newer listings that if you are not paying with Paypal within 4 days to please let me know so I can exempt you from the automatic unpaid item process, I then feel perfectly justified in rattling their cage on day 3 and opening a dispute on day 4 😉

No way would I ever mention feedback in a listing, or anywhere else for that matter.
