Make sure time is on your side. To make sure as many people as possible bid on your item, register your auctions to “end on a Sunday between 4 and 10 p.m. Pacific time.”
Appearance is everything. Using a “decent digital camera” to photograph your items will help attract attention and ultimately make a sale.
Don’t lose money on shipping and insurance costs. Be sure to include those fees in your sales price.
Honesty is your best policy, even as an online salesperson. “Be candid” when speaking about your product’s flaws. People appreciate and would rather deal with a “straight shooter.”
