Was selling an amp on Craigslist and this number texted me trying to scam me out of it. <br />The number said to go ahead and pack up the amp and his "movers" will be there soon. He will send a check through the mail to me - with a little extra on top no less!<br /><br />I'm in Houston and this dude was trying to scam me all the way from Maryland. When called out he quit responding. Wouldn't answer my calls either.<br />
