I have sold A LOT of items on UBID, but in general they tend to close a little lower than the identical item on EBAY.
On EBAY nearly all of my listings are no reserve starting price at about nothing, and they close at or even higher than what I would want on a Buy it Now.
I have not risked a starting price $1. listing on UBID yet - I just don't know if there is enough traffic to lift the price adequately. So on UBID I put a "buy it now" price maybe $400. or so above my minimum bid.
I have to be willing to sell at close to my minimum bid though, because the UBID buyers tend not to bid so much, at least with these types of listing. I may risk a $1. starting price soon - will let you know how it goes.
UBID will feature you on their home page or on the specialty page for your type of item if you list 5 or 10 at a time. Now, that is one nice thing. On UBID I can list $100,000. of stuff at once and they will not molest me. Doing something like that is what got me suspended off EBAY in the first place. They just couldn't believe that anyone could have that much merchandise - but I did, and do.  |
