Next we come to that list of nickel and dime (and higher!) marketing devices that eBay calls “listing upgrades.” These options are designed to make your listing stand out from the hundreds or thousands of similar listings in any particular category.
eBay recently added an option to insert a subtitle in your item listing, just below the main title. The charge is $0.50 for this option, and it's probably not worth it. After all, you can put all the details you want into the item description—what do you need the subtitle for? It's possible that an item with a subtitle may stand out on a search results page, but that's about it. Probably not a good use of your money.
