Directed at HVAC business's.
You could be contacted by e-mail, the "person" usually depicted as a female with hearing problems will inquire about the purchase of equipment. In this case 3 mini-splits for a friend or orphanage.
They will supply you with credit card number(s) that will initially work, and arrange to pick the equipment up at your shop. As this progresses the purchaser will suddenly have a family emergency and ask you to arrange shipment thru a nationally known shipping company that will not accept credit cards. You will be asked to write a check for payment to the shipping company and again charge the fees to a credit card.
They of course are being shipped overseas, in this case Ghana.
In this case the scam was found out well before the loss of any equipment or dollars...don't let yourself become a success for them, these people are very good actors and will try and get your emotions to lead you into doing something that you will regret!
