I've had plenty of auctions that I started at a dollar go up to 50, 80, 100, a couple past 200 dollars, so I'm happy with everything the way it is now. It's all been averaging out nicely for me, and DPW is a great place to sell in my opinion. It's the other people on this thread who are obsessed with price and mercilessly complaining about it.
As to bargain hunters, all I can say is that my experience here has put me in touch with people who have become regular buyers, some of them shelling out considerable sums when they see a piece they really like and the bidding gets going. The people I'm encountering don't fit into that mythical bargain hunter mold, but maybe someone else's experience has been different, I'll give you that.
Regarding the idea of someone using a minimum bid of say 10 bucks, as per your example, what makes you think that will guarantee a buyer and the ten bucks? It may very well be that no one thinks it's worth even that, and it still goes unsold, right? That's where the sheer craziness of some of these arguments comes in: Everyone just raise your prices to $100 minimum, and the buyers will come out of the woodwork, falling over themselves in a race to reward us for "respecting" ourselves and our art like all the 'experts" who write for art blogs tell us they will. Hell, that's magical thinking if ever there was such a thing, and it completely ignores the hard facts of economics 101: When you present a product that people like, they'll throw money at you. Present them with something they deem so-so, and you won't be able to give it away.
As artists we have to be real with ourselves and admit that sometimes we produce crap. And sometimes we produce something that may be great, but not to this audience. And sometimes we get lucky and present the right piece at the right time to the right audience and they then give us money and we feel good. That's why it's important to put something out there every day, as a way of increasing your chances of winning.
I just wish people would get that.
