A fast listing is only useful when it is the right comic, in the right condition, attached to the right postage policy. Comicz removes repetitive entry; it does not remove the final check.
Connect the selling account first
Authorise the intended UK or US eBay account. In Seller Hub, create active payment, return and postage policies and confirm the ship-from location. Comicz cannot invent missing business policies, and a failed policy is not fixed by repeatedly pressing List.
Photograph for the buyer, not merely the scanner
Use a square front cover for identification, then add the spine, back and any material defect. Slabs need a readable label and glare-free case. Buyers should be able to inspect the same flaws mentioned in the description.
Review the draft in order
Confirm series and issue before touching price. Then check variant, printing, year, grade or condition, quantity and description. Automatic pricing is evidence to consider, not a valuation certificate. Preview the buyer-facing result.
Recover without duplicates
After a timeout, look in eBay Seller Hub before retrying. If the listing exists, sync it back to Comicz. If it does not, correct the reported field or policy and retry only the pending channel.
