For comic sellers on eBay and Whatnot
Photograph the comics the way you already do, upload the photos, check one screen, and download a file eBay accepts. Titles, item specifics, condition, shipping, store category and photos are written for you. You upload the file to eBay yourself, so nothing goes live without you seeing it.
When you create a batch you tick where it goes: eBay, a Whatnot live auction, a Whatnot Buy It Now store, or any combination. One set of photos and one review screen make the eBay file and the Whatnot files (the show file with your opening bids, the run-of-show sheet, the Buy It Now file). After a show, paste the sold custom labels and the product hands you the eBay End file for those comics; drop eBay's orders report on the pick list and it names any comic that just sold on eBay while it was also in a Whatnot batch. The same comic is never for sale in two places without you knowing.
It will not list anything for you: you approve every row and you upload the files yourself, on eBay and on Whatnot. It will not price your comics: you type a starting price for the box, and the screen flags the ones worth more. It does not crosslist to ten marketplaces: it is built for eBay and Whatnot, which is where comics sell. How it compares with the crosslisting apps, side by side.
The item specifics eBay searches on for comics (Series Title, Issue Number, Era, Publisher, Unit of Sale) are filled in the way eBay wants them, each listing is routed to one of your own store categories (lot, complete series, graphic novel, back issue under the price you set, rare find), magazines never go on Media Mail, and a lot's title names its issues so buyers can find it. It started as the tool one seller used to list his own long boxes, and every rule in it is one that a real upload taught him.
Your first 50 listings are free. A card goes on file before your first batch is read; nothing is charged until the 50 are used or 30 days pass, and cancelling before that costs nothing.
