The one's I've seen in the past said you could only pay with I think it was Western Union or some such method that you cannot get your money back. Scam.
When I was like 15 and dumb, I got scammed by someone shipping a MacBook Pro on Craigslist and I paid them using Western Union. Then they ghosted me right after I told them I sent the money.
I did some digging around that night and found posts online word for word like the listing I saw and realized I fucked up. Tried to figure out how to get my money back and everything I read basically said if you paid with Western Union, your screwed. Went back to the place I sent the wire transfer first thing in the morning and somehow got my money back. Still not sure how I was able to but I’m glad I was and never doing that again.
