Actually, there is not enough details here to figure out whether this is an OK (not great) buy or not. If all the points are there and the seller has already paid the dues on all the points, then you may be getting a better deal than buying directly through Disney at $84 per point. Yes, it is inflated and probably ridiculous, but it is possible that someone may make out better with this resale than buying the same number of points at BCV through Disney.
Just a thought.
