eBay's Listing Designer
How many times have you seen an item on eBay laid out on the page all pretty with a decorative border around the description? If that sort of thing appeals to you, eBay's Listing Designer will supply you with accents and borders for almost any type of item for $0.10.
Selecting your design is as easy as clicking the menu. You can designate where you'd like to place your image on the page relative to the description (left, right, top, or bottom).
Will the pretty borders increase the amount of bids your auction will get? It's doubtful. A clean item description with a few good clear pictures of your item is really all you need.
There's a special combination deal called the Value Pack. For $0.65, you can place a subtitle on your listing, add a Gallery Plus picture (a larger version of your picture in search results), and doll things up with Listing Designer. All those features would normally cost $0.95, so you can net some savings if you run several listings a week.
