I sale a lot of items on Craigslist besides Ham Gear and have had many of these scammers contact me. I let them send me their fake cashiers checks (they overnight them) and claim that I have deposited them and that they have cleared my bank. (I drag this out a little to make the squirmy.) I then tell them that I am going to send the money to Their Shipper but drag that out a little while to. I then tell them that I sent the money western union and they ask for the number of the money order, I ask if I can just send a picture of it and they say yes, then I send them a picture of a banana or something. others I tell I got intoxicated and spent the money at a girly bar. some even call me on VOIP and we have delightful conversations. I have collected over 30 fake checks this way. "advert" is one of the many tell tell words they use. Please be careful all. More than likely If you cannot have a phone conversation with them then they are not legitimate.
