As a reminder, Sellers can’t have more than one Fixed Price listing of an identical item at the same time. Multiples of identical Fixed Price items should be offered in a multi-quantity Fixed Price listing.
If you list duplicate auction-style listings, only one listing without bids will appear on eBay at a time. Once the first listing receives a bid or ends, the next auction-style listing for the same item will be eligible to appear on the site.
If you have multiple Auctions running, try to stagger their end time to increase bidding activity.
