FB marketplace is a terrible market. It does not allow exact searches. It forces scrolling hundreds of ads in the hope of finding what I need. Even Craigslist had (has?) far better searching. If you do something crazy like sort by distance half the ads disappear. It is full of scam ads (I have given up trying to buy used phones, for example). Sadly I am forced to use it because that is where all the local person-to-person selling happens.
