Check out and emulate the best of the competition! There is no worse feeling than to have sold a very expensive item for a very low price because you did not know its value. If a brand is unfamiliar to you you might also not know how to draw bidders to your site to bid on it. Do searches for items similar to yours. Take a critical look at the ads and pricing – especially if there are more bidders and higher prices. You can learn much from your competition. Shamelessly steal good ideas or take a reasonable idea and make it even better.
