Overpayment Scam - Alabama Exercise Equipment Re-seller

I was contacted via text about a Bowflex Home Exercise machine I was selling. The phone used is 205-538-2140 and the contact used an email address of [email protected]. Contact originally said would send a check for the full amount it was advertised for $650 and would have equipment picked up because they are an exercise equipment re-seller. Later tried to suggest he/she was sending a check for the equipment plus shipping. I ended contact today and am not taking this any further but I thought I should post the contact information so others don't have issues.
