I am not on Craigslist, but wanted to help and tell you what would happen if you had agreed to have them buy your item. Once all the shipping arrangements had been made, they would send you a check for far to much than they owe, and you would have to send the money you owed. It also gets even worse when you try to cash the check, and are told that it is a bad check. So, really all this time, the scammers were the only ones receiving the money. I could be wrong, but I think these scammers have special computers that send these messages out to a ton of people. I am positive many others will receive this spam message in a short amount of time. It is simply best to ignore these.
What is up with these dumb [***] people. This person texted me interested in my cell phone for sale. I immediately googled the number and came up with this page. As I am reading the above comments he texted back and surprise, surprise they want it shipped to the girlfriend in Africa! I wish these people could be made to be held responsible for their attempted scamming.
