Obviously, not everyone who sells office supplies by phone is part of a scheme. But there are certain 'red flags' that may help you recognize the common elements of a scheme to defraud you: 1. The supplier is in distress. He is being forced to liquidate the stock; someone made a mistake; or the merchandise was shipped to the wrong address and he needs someone to help him out. 2. He is vague about the location of the store. 3. He casually drops the name of the Chairman of your Board, corporate treasurer or other officer as having suggested you might be contacted. 4. He is unlikely to have a sales catalogue which can be mailed to you. 5. He wants a decision right now. Also, be wary of the telemarketer that calls wanting the ID number off your copier. These peddlers specialize in copier paper, toner and supplies which they represent as the 'brand name' product. However, on close questioning, they will sometimes admit that it is 'just like Xerox's', 'authorized by 3M Company' or 'the same as IBM.'
