Reach more buyers and generate more interest in your item by listing in two categories. For example, you could list a vintage table from Japan in both the Asian Antiques category and the Antique Furniture category.
Fees
Listing in two categories increases your Insertion Fee as well as the fees for most listing upgrades (Bold, Gallery, and so on). Fees for Scheduled Listings, Home Page Featured, Motors Home Page Featured, and Final Value Fees remain the same whether you list in one category or two.
For specific fee information, see the Listing Upgrade section of the Fees page.
