eBay is offering a special promotion for its storefront owners who list items with a "Good 'Til Cancelled" feature. Sellers listing items in their stores from May 20 – May 22 with the special feature will receive the first 30 days of their listings for free.

The Good 'Til Cancelled (GTC) feature allows sellers to list items in their stores that will automatically renew every 30 days. Listing fees apply each 30 days. eBay will charge sellers the current standard GTC listing charge ($0.05 per 30 days) after the first 30 days. If sellers don't want their listings to renew, they can select the 30-day duration, which will also be free during the promotional period. All other fees (Gallery, Bold, Featured Plus and other feature fees) and other Store Inventory extended duration surcharges will still be charged.
