  • Now that David's kids have grown up, he has more free time from them to list more. He plans to expand the items they are doing on eBay. Their store itself will probably expand as well doing a lot more. They may start to offer some items directly from their own website in addition to eBay. It would be for items that for some reason don't do well on eBay.
  • David hopes his business would continue to grow at the rate that it has grown over the last few years.

Advice, Tips & Tricks

  • To ensure a 100% feedback, you should take a great deal of describing and taking pictures of your items. In creating a description, imagine the person who is going to buy the item as your friend. Your friend picks up the item and asks, “what is this?”. Your answer to your friend would be the description of the item. If you type it this way, the person on the other end will have a clear picture of what he/she is bidding on.
  • To keep your business going, David recommends to observe these basic rules:
    • 1. You have to price your products competitively.
    • 2. You have to take seriously the way that you are perceived by people on eBay. It does not just mean on feedback, but in means on proper spelling and punctuation.
