I think this is a scam number.  I had several ads on Craigslist and I received the standard scammers message about sending me a check and he would arrange for his people to ship it. yada yada then later I received a text about a computer I had on there, as well...The person actually answered me back when I asked if he was still interested and wanted to come and see it, he replied what was the least I would take then no answer.

I texted him back and said I see he is the same number that texted me about a cage that I had for sale...... Obviously I won't get a message back from him
