This. Sure, the cost to reholder is $12, but it's gonna cost you at least $15 to send the book to CGC and it's gonna cost like $32 for CGC to send it back to you. All said and done, it'll cost at least $60 to reholder the book. I had this happen to me before, I reached out to the seller who immediately apologized and offered me a $30 refund to cover reholdering. I knew reholdering would cost more, but it was a book I REALLY wanted and I didn't mind spending an extra $30 on a 4 figure book so I just covered the remainder myself. I'm of the state of mind that the seller is on the hook for making sure you're made whole or compensated to your satisfaction up to the cost of reholdering (assuming the book is undamaged). If the book IS damaged, then yeah, return that puppy and get a full refund. It is the sellers responsibility to file an insurance claim with USPS, not yours.
