eBay Error 89: eBay does not allow Dutch auctions (or a quantity greater than one) in the category you have selected.

Why this happens

The listing's category does not allow Auctions or items with an inventory. Why eBay enforces this: Some eBay categories, such as vehicles and certain collectibles, only allow one item per listing and may not allow auctions with more than one unit. eBay enforces this so each unique item gets its own listing. When it usually happens: It usually appears when a multi-quantity product is mapped into one of those categories, or an auction template with quantity greater than one is reused.
