More than one auction-style listing for identical items, including auction-style listings with a Buy It Now price, as long as the seller's sales history for duplicate auction-style listings is successful.

Two or more auction-style listings for items that are not considered "identical", such as:

Two or more listings that show differences between the items in the title, price, photos, subtitle, product ID, item specifics, or parts compatibility areas of the listings.

One listing selling multiple items that are identical.

Two or more listings to sell bundles or "lots" of items that are very different and clearly satisfy different buyer needs. For example, listing a pack of 10 envelopes meets one buyer's needs while a pack of 100 envelopes would meet another buyer's needs.

Two or more listings where the items are the same but are in different conditions, such as 1 new, 1 used, and 1 refurbished item.
