@SpreadsheetSnorlax asks
I found my card's price but mine is in a slab. Can I just add the grading fee?
Jeff answers
I wouldn't add the fee mechanically. Start with the exact card in our app, then look at sales for the same grading company and grade. The market may reward that slab by more than the cost, less than the cost, or very little. Your expense and the buyer's willingness are separate.
