I have been down the Craigslist road, i'm telling you now, ALL SALES ON CRAIGSLIST NOT DONE FACE-TO-FACE ARE SCAMS, THERE'S NO EXCEPTIONS TO THE RULE. It may seem fair and a good deal, IT"S A SCAM.
Shipping transactions are done through eBay or Amazon... NEVER CL
Disclaimer: I really shouldnt say ALWAYS a scam, but rather 99.99999999999999999, that leaves a .0000000000000000001 chance of this guy being legitimate.
