Two years ago I bought the following book from kellyssuperheroes on Ebay: Incredible Hulk #6 F/VF 7.0 White pages Unrestored 1963 Marvel Silver age ( 311493615217 )
I sent it to CGC to get graded and it came back 5.0 Universal grade with off-white to white pages, so at least it wasn't restored. I emailed kellyssuperheroes to complain about the overgrading, since 2 full points overgraded on a $500 comic book is pretty significant. His reply was that the price I paid of $500 wasn't significantly higher than a 5.0 grade Hulk #6 was worth and I should be happy with it.
I replied back that I also had to spend roughly $68 dollars to get it graded, so I'm into the comic for $568, which at the time had a GPA average of like $400. I asked if he would at least refund me the grading fees of $68. From that point on, he just ignored my emails.
