New scam on Facebook marketplace?

Is there a scam on Facebook that does not involve pay ID? I’ve had four enquiries for two seperate items that very quickly offer cash. For one of these items I accepted, gave my address, and the guy said he would drop off his wife and then come. But he never showed up. This wouldn’t be so remarkable - but his profile was that sketchy kind - genuine but still generic photos, weird tone about them, always in a language other than English. I’ve had three other interactions that are similar- very pushy offer cash, ask for address. Is this a scam?? How and what for? Unfortunately I gave out my address to another guy that never turned up.

Perhaps they’ve caught onto to people clueing up about the pay ID thing, and trying something else. But why did two guys not turn up? In the space of 24 hours.
