<prompt> Human: I am planning to move so I am selling a lot of items on Craigslist. I have had 3 people offer to pay me more than asking price. Is this normal? Granted, the items are rate, antique dollhouse and a special jeep top. But it just seems fishy. All 3 preferred email contacts. And want to mail a certified check and will arrange pickup after the check clears. Any chance this could be a scam?  <response>: IN-PERSON CASH ONLY AT BANK OR POLICE STATIONElse, SCAM.
