Duplicating is kind of like human cloning, but without the ethical questions and funding dilemmas. Duplicating makes a copy of the fields and pictures from one item and pastes them into a new item. You can then edit the new item as you see fit. It works like this: From the "Selling > Add or edit Items" page, click the "More" link on the tool bar above the item you want to duplicate and choose "Duplicate" from the menu that appears.
Let's say that you're selling a 1999 Honda Civic, blue. You also happen to have another blue 1999 Civic with a small stain on the driver's seat (cops ain't gonna catch you riding dirty). Rather than fill out a whole new item form to get that second Civic in your booth, you could mouse over the first Civic, click "Duplicate," then edit the copy to include that bit about the stained seat.
Please note that duplicate listings are not permitted on Bonanza. The "Duplicate" feature is more of a template that lets you enter details for an item and re-use that information on another listing, which you can then customize without having to re-enter all the overlapping traits and details again. To prevent sellers from inadvertently violating Bonanza's policy by listing duplicate items, the duplicate feature will not copy the following fields:
If you have more than one quantity of an item, you can set the available quantity in your new item form, or via the batch editor.
