I have a suggestion for you that might add to the bids you'll get. Few of us have as many credits as we'd like and I'm always bidding on loose gemstones or watching auctions for them. If I lose an auction I will bid on the next I'm watching, provided I've gotten my credits back fast enough. You have a bunch of loose opaque gemstone auctions going, each ending in a minute or two of one another. I emailed Listia once to ask how fast one got their credits back when one lost an auction and the person didn't know so I still don't either. If it takes more than a minute or two, I won't be able to bid on your next auction and so on. I guess I'll find out how long it takes if I'm watching an auction I've bid on and lose, then watch to see how fast my credits are returned to me. And do that perhaps three times to see if the time frame is consistent. See, two heads ARE better than one, LOL. :))
I've wondered about that myself,and apparently If you get outbid most of the time your credits are back immediately,but if the site's really busy there can be a lag.And if you win an auction for less than your top bid,you get the extra credits back as soon as the item moves to your Auctions I've won heading,but that timeframe seems to be pretty random!Lol!
