I purchase sometimes from particular vendors because delivery is "guaranteed by" certain date. But it is not! The vendors lure you by "guaranteeing" delivery by certain date, and eBay colludes. Then you learn you aren't getting what you were "guaranteed". I lost certain opportunity because the purchased thing arrived 3 days after "guaranteed" date. And eBay does not care, and continue to lure again and again. They should be not "guaranteeing" it then. They could say something like "delivery date target is", but not "guaranteed". Thys should lose that one in court. They guarantee is a binding contract, which they do not honor, and just continue to violate it. My last not-so "guaranteed" item was #122856222054.
