I wouldn't want to be the Direct Marketing company in this situation..

11,000 customers of the Harrahs Joliet Casino in Illinois had cause to celebrate last week as a coupon misprint gave them $525 in cash - instead of the $15-20 it was meant to offer

Annoyed customers were told the casino wouldn't redeem the coupon for cash - but to trade it for points - but the Illinois Gaming Board told Harrahs they would have to honour the coupon
