Check this one out before you do anything. My son was selling his motorcycle and someone answered right away wanting to send him a check and someone was going to pick the bike up. Anyway, it was a scam because by the time you went to the bank with the check, the bike was gone and the check bounced and you can't find the person who wrote it. They say they're cashier's checks and look like them, but they're not what they seem. Anyway, there's a site you can check out this kind of scam. Just be careful. Wouldn't want you out your machines and the money.
