Several yrs ago my BIL found a sweet deal over the internet in Florida. After many emails, he informed them he was coming to look at it and was bringing me.
The ad disappeared immediately. Temptation can be so strong sometimes that it clouds our resistance. I believe he would have sent them money to secure the deal if I had not been able to convince him the deal was just too good. After his mind cleared he thanked me for saving him a hefty sum of money. The scammers have a new wrinkle every time, they are very clever.
Do not send money
