Shipping occurs Monday through Friday barring closure of the post office for a holiday. Your item will typically ship within one day of receipt of payment. Your graded comic will ship well protected and boxed via USPS Priority Mail. I will be happy to combine shipping fees. Send the combined shipping request through eBay, and I'll send you a new total usually the same day. I like to pre-package your multiple items so I can give you the most accurate shipping estimate. Shipping is restricted at this time to the United States.

Feedback will be left for your upon receipt of payment. I would appreciate return feedback once you receive your item(s). If there are any problems with your shipment, please let me know right away so we can work out an acceptable resolution before leaving feedback.

Newton rings, if any, are minimal and do not detract from the presentation of the graded comic for display. Newton rings present as concentric circles giving a rainbow or oily appearance. There is NO oil or moisture in the slab. This is simply an optical interference phenomenon between light reflecting from curved and straight surfaces (the slab and the inner comic seal). In older slabs with the semi-open sides, it's possible to run a sheet of copy paper through it sideways to break the contact between the slab and inner seal, with no damage to slab or sealed comic, to alleviate the problem.
