Don't buy an RV with Gift Cards

DW used to work in a store that had Western Union money transfers. On many occasions they had to talk their customers out of sending large sums to criminal scammers--everything from "your grandson is in a Mexican jail" to "the IRS is going to take all your stuff if you don't pay immediately". Usually a couple of questions from the cashier was sufficient to recognize the scam. Sometimes they succeeded in keeping people from giving their money away, sometimes not. And as mentioned above, not all of these folks are morons. Some are scared, some just got fooled.

Keep your guard up.
