The only thing worse than a reserve price, is a seller who won't tell you what the reserve is. Better to just set the base price at your "reserve" price so everyone knows.
Wherever you list, having good pictures, honest description, without a lot of fluff promotion work best. Just the facts.
When someone tries to hype a product as being so wonderfule, awesome, amazing, my eyes glaze over & I skip to the next item.
