I'll certainly combine shipping on multiple purchases and will run periodic shipping specials, including free shipping (subject to terms). Qualified orders will ship with delivery confirmation and many transactions will include insurance.
As a general rule, all sales are final, but I am customer oriented and will do my best to correct any errors on my behalf.
For ungraded, or raw, cards, I will list any perceived flaws, but I am in no way qualified as a professional grader and will not attempt to assign "potential" grades. I will however provide detailed scans and answer any questions about items I list.
