I think the sneakiest scam I've heard of yet is where a delivery man pulls up in his delivery vehicle with a gift basket and a bottle of wine. He then says it's a delivery from a secret admirer. As you reach for it he hands you the basket and says since there's alcohol he has to see your id and process a $2.50 liquor tax fee. Then he runs off with all your info while you happily munch at your $20 gift basket.
Wow that's the first time I heard of that one!
I recently had a call from NV stating they had someone in my area looking for the EXACT boat I was selling and they said they would finance the buyer exactly my asking price of $11,000.....he asked if there were any issues with the boat I said the transom is rotted and the engine is about to fall off....he said "are you serious" and laughed......he said he had to talk to his supervisor and he will call me right back, never heard from them since. I live in Connecticut by the way.
My other favorite is the texts about 5 minutes after posting the ad "I'm willing to pay your asking price plus $500 if you delete the ad now and send me your exact address and full name, my shipper will come and pick it up after the check clears" I usually send them something extremely rude back.....and never hear from them again.....
I actually know someone who fell for one of the scams he paid for a truck sight unseen, some where around $2,500 and the ad screamed to good to be true, once he wired the money never heard from the person again....and guess what? No truck
