Thanks for all the best wishes and replies. This is what I figure and what has happened so far.
#1 I bought through the seller directly, no ebay, just talking on the phone and paypal. So there's no way it violates ebays policy's people sell stuff directly through paypal all the time.
#2 Bought with credit card that does have protection. I won't get Ebay protection but I do get paypals and the credit cards.
#3 The seller has good feedback and has legitimately sold many of them.
#4 The shipping was delayed due to my circumstances. I was away when it would have been shipped, and told the seller to hold off on shipping it until I was home to safely receive the package. Not about to let a rMBP sit on my porch for 2 days.
#5 I have been in constant contact over the phone with the sellers personal cell. The contact info is legit and if something were to go wrong I have a good amount of information.
#6 The deal...more than worth trying to see if I can snag it for 1700$.
#7 I will know what exactly is going on/ what will happen in 24 hours
I'm trusting all will go well and I hope it does. But if it doesnt, yes I screwed up and got scammed, but will I fight to get every dime back and that seller reported to paypal and ebay. Not to mention I work for an agency I will not name, but let's just say they provide a legal way to handle thieves and or scammers. Like I said I hope it just works out for the best and ya know a deal is a deal, but then again ***** happens and you have to handle it.
