I did start with low bids on ebay just to get seen. I figured I could 'lose' a few pieces and take a risk. But there was always a last second bidder, with a low bid. DPW has taken care of last second low bidders by extending the auctions when there is activity on a piece. BRILLIANT! DPW also list every new piece daily on one page, and in many different ways, this is an all art related site, they've kept the scammers out and for those reasons, I didn't think it was necessary to do on DPW. Listing at $1 or less than the cost of materials even, devalues the work in my opinion.
And if a piece doesn't sell immediately, it may sell later. Fill in keywords and description to come up in searches and when you continue to list new work, buyers will often look at more of your work. That's how I sell. Of course, more would be better but isn't that true for anybody?
