Ed Grogan, a salesman with Maus and Hoffman stores in Fort Lauderdale, Fla., displays the ultimate wrapping paper - a sheet of uncut dollar bills. Each sheet sells for $55 - $23 over face value. The stores go through 350 to 400 sheets each holiday season. Because many gift recipients don't realize the wrapping's value, a sticker on each package warns: "Destroying this gift may be hazardous to your wealth."
