Looking at it, it appears to be more of a FB marketplace or Ebayish location where people are selling used (or new) stuff as individuals. Like CL, FB marketplace, Offerup, KIJI, or Ebay mostly it will depend on the individual item and seller as to whether it's a crapshoot or not. I don't know if there are any "buyer protections" ala Ebay so I'd tread carefully.
