I wouldn't advise that strategy here. Start your listings at a price you would be happy with, set them to go for a decent time (I used 14 days, others 7) and 10 autoreposts, List, list and list some more, use bin so you get google shopping presence, promote.. facebook, twitter, with flyers in your sales on other sites and then you make sales here.
I've been here a while and I'm now making daily sales. My feedback, like that of many sellers, does not represent anything like the full picture. Less than half my buyers leave feedback.

I don't think the above eBid knowledge base link can be posted too many times on here.
