Facebook marketplace is a huge buying and selling store. You can buy/sell everything you could imagine by category. Mainly people use this app to buy stuff because you can interact head to head and not have to deal with a dealership or a store, depending on what your buying. This app is just like SWAP, that is just selling and buying mostly clothes.
Now moving on to the (pros) of using this app, like i said before it's all in person and trust worthy. Yes there may be some scams on this website and that is why before you go look at or pick up what you're about to spend your money on, give the dealer a call or a text making sure he gives you all the information. A lot of people have been scammed on this app but a lot of people have been pleased with their outcome.
Some cons are…just trust, depending on how much you can trust. But aside from that, like I mentioned, people have been scammed and some have not and sometimes you just have to be smart with your senses and money. Example is, if I wanted to buy a 10,000 dollar truck or car it is either gonna look really nice and have everything wrong with it or I could buy one with everything right with it but ugly, and especially with the truck prices people would go with a car.
Personally I go on marketplace on occasions just to browse the trucks and cars for sale, most people go on the market to look at, cars, trucks, parts and essentials for a vehicle, marketplace serves many purposes and people sell everything but clothes on it(new things to old), so yes I do trust marketplace if I get ahold of the seller and talk about the information.
Do you shop on the market?
Have you ever bought something off Facebook?
