So I have taken about three books to my local comic store and had them sent for grading, but unfortunately he has closed the shop and I have several comics I want to get graded, I have some people tell me it costs 20.00 a book to grade and cgc saying I just need to buy a membership but what’s the catch,or is there I pay $$ and I can send in as many books listed for that membership for the year? I was getting charged 20.00 per book to get graded from comic store I’m a noob at this whole grading thing and would appreciate any feedback. Thanks in advance!
