The Better Business Bureau says three sweepstakes companies are running scams.
CDN Financial, TD Financial and P. & A. Financial are the companies listed in the BBB consumer alert.
The BBB says these companies are mailing letters to people, saying they've won up to $525,000. The award letters include a check that is supposed to pay taxes on the winnings. The BBB says the checks are counterfeit, and that these companies are running a scam.
Remember, officials say you should not have to pay upfront on a sweepstakes win.
