The United States Post Office raised shipping prices AGAIN but we do combine shipping for multiple purchases so you can save money. Shipping is $4.99 for the first comic and 50 cents each additional comic. I use a comic book grading tool for grade estimates. Most modern comics will be NM and I will not use the grading tool unless I see flaws. Pretty much anything Bronze/Copper age and older will have a detailed breakdown of why the book received the grade it did. The grading is fairly accurate as seen in my feedback. Contrary to popular belief by many sellers on this site grading isn't too subjective and as a buyer and collector of comics when I see a seller saying "im not a professional grader so use the pictures to judge for yourself" is a red flag for me. I generally will not buy from a seller if I see that in their listings. All items will ship within 5 business days of purchase but usually ship in a few days. I have the 5 days handling time just in case.
