Apparently, searching on Offerup is limited to exact matches only. If I search for "Denon 5308" it does not show Denon AVR-5308CI, Denon 5308CI or any variant of "denon 5308". In actual fact, it does not show Denon AVR-5308CI How difficult is it for a company that has been in business since 2011 to start emulating what their (far advanced) competitors (like eBay) have? Offerup will always be an "also-ran". Boolean searches? Too far advanced when simple searching is way too frustrating - wading through lots and lots of "denon" to get to a particular model I know I want! Or maybe, Offerup just want us to boost our data usage.
