i got a suspicious message from this number as well. i don't have any proof its a scammer but im not selling my item to them and shipping while using paypal. i had a local listing. weird how someone in california cannot find electronics in a local pawn shop. haha
I also received an email after posting an ad on Craigslist in Colorado. They have VERY poor english.
This was the message:
"Hey am Rebecca...I would like to make a purchase of you item..You can text me at this number (650) 307-6322 please include your Name"
