Long story short, I posted my iPhone 3GS on Craigslist and received the typical spam emails and people low balling you. I originally posted it for $450 OBO cause I figured dealing would bring the price down anyway. I received an email from a lady today asking if the iPhone was still available. I replied that it was and that the first offer gets it. She sent me this reply: Thanks for your prompt e-mail. I hope the item is in good condition and i will like to purchase it for my daughter in school out-of-state.and i will be very more than happy if you can help me get this item shipped, and am willing to offer $600 to include the shipping fees through the USPS Express mail service, i will be paying you with my PayPal account,If my offer is accepted send me your email with PayPal including your phone # so i can pay in right away..I work on the sea and do not have much time around me. Make sure you get back to me so that i can arrange for the payment I await your reply I start reading the email, see she added $150 to the price and the red flag went off. I continued reading and then I hit......USPS Express......and PayPal.......doesn't seem like the typical scam where some skinny wants me to ship my phone to Nigeria while overpaying me and requested the difference back. I just wanted to double check before I blew this off as to if it could possibly be "real". I know, the too good to be true, and it is.....but, what would they go through the trouble of USPS Express AND PayPal??? Any ideas? I will be sending a follow up email requesting where the phone will be going as I will only be shipping within the US. Thanks in advance!
