|Set up your Q&A|
Buyers often have questions before, during, and after a sale. When they do, they click the Ask a question link in your listing. As a seller, it's important for you to respond quickly and thoroughly. This keeps the buyer interested in your listing, saves you time, and you'll be more likely to get positive Feedback when the transaction is complete.
Your Q&A can be made up of answers generated automatically from your listing, answers you create yourself, and stock answers about eBay policies. Up until the end of the listing, you also have the option of whether buyers can contact you directly.
