Would you feel comfortable buying a rMBP off eBay that comes with AppleCare? I found some good deals, and they claim to come with AppleCare. The seller has 100% positive feedback with over 500+ good feedbacks. Everything they sell is Apple hardware, mostly laptops. The price is good, but not outrageously unbelievable (doesn't seem like a "too good to be true" price). I have sold several computers (some MacBooks) on eBay, and I would hope that there are other sellers as honest as I feel I am, but I know it's a huge marketplace with plenty of scammers mixed in.
