Facebook Marketplace has completely taken over in most parts of the US. It sucks.
But there's one simple, guiding principle that I'm always following. And that's refusing to reactivate my FB account.
That said, I've definitely had less success on the sales side than I did in years prior, but I can't tell if that's what I'm selling being worth less used these days (desktop computers?), or if Facebook Marketplace is the de-facto place to check.
Boston has a lot of good stuff in some areas. Need random leftover shelves? A pile of screened loam? Secondhand office furniture? An unused China set from the 1960s? No problem. But good luck trying to buy and sell normal home goods with any efficiency there; it will clear much much faster on FB marketplace. Maybe even for a better price.
