Additionally, the Voyager episode "False Profits" featured Neelix telling two Ferengi stranded in the Delta Quadrant that rule of acquisition number
299 was "When you exploit someone, it never hurts to thank them". We do not know if this is an accurate quotation; if it is, then we would need to believe that the Ferengi have added extra rules sometime prior to Voyagers accident and that Neelix has read up on these since.
In DS9's "House of Quark", Quark himself suggested an additional rule: Rule 286, "When Morn leaves, it's all over". Quark was bemoaning the state of his business at the time, and it is unlikely that this rule is a real one.
