1. Gather up a list of items to sell
Go through closets, drawers, basements, attics and your room to find items to list. Anything that you haven't used in the last 12 months is a candidate to sell.
2. Search for Completed Auctions First
Search for your item to see how much a recent copy sold for. A good strategy is to offer a few bucks less than the last version sold to get a quick sale.
3. Take Great Photos
Your photos and description sell your items. Use a good digital camera and/or scanner and take clear pictures.
4. List Your Auctions to End at 6PM PST
This is the best time to end your auctions because people are off work and at home looking for stuff to buy. The best day to end an auction is Sunday night. The worse days are Friday and Saturday nights.
5. Ship Your Items Fast
Try to send your items as soon as possible. Don't wait longer than 2-3 business days to ship your stuff.
