There are numerous ways for you to ensure your clients receive excellent customer service from you while conducting transactions on eBay. The first thing you have to do is to act quickly at closing of auctions by congratulating the winner. 

Though the buyer is aware of the description of the item, give them another description and give them payment options and instructions for paying for the item. Also inform them about the date the item would be shipped to them. 

You could end your email with a thanks note for taking part in your auction; and perhaps inform them of other auctions you have.

On sending the item, inform the buyer of the date and time of shipping of the product, and when it is expected to reach them. Follow up by finding out if the product had reached them on time or not.
