I dont think that the negation of a possible return (due to getting the book SSed and there being some damage as a result of the SS process) excludes a partial refund.
poor handling didnt make the book restored, it just made it go from a 9.0 to a 6.5
A 6.5 has a 12mo GPA average of $186, there's not enough data to say what a SA 6.5 is worth... A SA Stan Lee in 9.0 was worth 45% less than the universal version. So Say a restored 6.5 is worth half of what a blue 6.5 is worth. controlling for slabbing costs (say $40) that means you should refund him 50% of 146, so $73
does that make sense? (Im not sure myself, so Im going to leave it at that, and get some sleep...)
That makes sense but I would disagree with the PLOD being worth half of the Blue. I think it would be less than half.
