All grades are fair estimates, please take a look at pics and my feedback.  Shipping to USA and Canada is $18.00.  I do combine shipping.  Country of manufacture is USA and falls under the HS code heading of 4902.90.20.60 which falls under description of "Other -  Other business and professional journals and periodicals (including single issues tied together for shipping purposes) which means there are "no duties" to be paid if shipped to USA from Canada. NO TARIFFS - as comic books fall under CUSMA (Canada-United States-Mexico Agreement).  Please be aware that customs makes the final decision and the buyer is ultimately responsible for any tariffs, taxes, brokerage fees, duties etc
