I have a CL story....
Wanted the specific "early 2009" 2.66 15" uMBP model.
Called seller A: spent two days going back and forth, then two hours before meet, get an email saying she no longer wants to sell.
Call seller B: lives less than 1/4 miles from me, Selling NIB...great! Schedule to come get it when he gets off work. Never calls, never responds to calls/email/texts.
Call seller C: best deal ever!! Send emails back and forth. Try to meet at Starbucks next morning. I show up, email via phone to call me. Get response that is gibberish (like programming code). Send another email, receive gibberish response again. Go sit out in front of Starbucks next to guy on the phone who keeps calling wrong number repeatedly. Guy leaves, so I leave thinking it was too good to be true. Send email to guy saying I was here and please call. Get gibberish response again. This time try using phone browser to check email this time. Receive emails that I can read and finally get guy's distress calls and phone number. Call him, Says he was there and called me but number was wrong. Gives me his number and tells me number I gave is invalid. Quickly realize I typed wrong number on my touchpad Instinct. Whoops!! Guy says he is close by and will come back. Guy shows up and was the one who was less than one foot from me calling the wrong number earlier. Oops!! My bad.
Laptop was as promised so I laid out $1750 in cash in the back of his SUV, and the rest is history...
So, it does happen. There are some people who have saved and are looking for a used MAC at a good price. Guy gave me copy of his receipt and I paid for $1750 for a brand new $3328 purchase at a MAC store just two months prior. That’s after the “educator” discount too. I did not pay attention at first but I crapped my pants after actually reading the receipt.
I sell a lot of stuff on CL, and I get mostly scam emails and people offering $10 for a $100 item. You just have to be patient. A lot of people sell things for much more than what they are worth, but if you post a fair/market price, someone will eventually buy it.
