I really disagree with the advice to undercut the other sellers. I think you could have a "grand opening" promotion sale and discount your stuff for your first week to hopefully get some attention. But setting your prices at half the competition? Thats bad business. First of all, theres lots of people giving stuff away for free. And they probably give more away than I will ever hope to sell. How can I undercut 0? You should sell at the price that generates the best price-to-sale ratio. For example, if you sell something for 500 and sell one a week, but the same item sells 6 a week if priced at 100, then it makes sense to sell it at 100.
