I don't answer any calls I don't recognize. But today I got a $2850.00 check to do a mystery shopping trip for Ebay gift cards. I had heard of these before and a few years ago I got the same thing for Target. I don't shop either one. After researching the name Richard Fels, the sender, I shredded the check and letter. I knew it was a scam but I researched anyway to see how many other people had received the same thing. He seems to be a busy fellow with one site having 455 complaints. You are supposed to deposit the check, keep $400.00 as your fee and then buy Ebay gift cards with the rest. Scratch them off, photograph them and document your experience and send to him. Bad thing is the check is fake and you are responsible for the money. There are probably people that fall for it, but unless I return to work, nobody is sending me a check!!
