What is Store Inventory Format? If you have an eBay Store, you can stock it with additional fixed price (Buy It Now) items that might not be cost-effective for you to include in regular eBay listings. Benefits of the Store Inventory format:
• List for just $0.02 for each 30-day period, regardless of quantity.
• List for longer durations - 30, 60, 90, 120 days, or Good 'Til Cancelled.
• Use the Gallery picture feature for just $0.01.
Store Inventory items appear in your eBay Store alongside your Online Auction and Fixed Price items.
When buyers visit your Store, they will see all of your listings – in all formats.
