Since this wasn't the first Auction with the +5 Minute rule, I assumed everyone knows how it works.

For those that don't or participate in my Auctions here for the first time, there is the note to ask ahead of time to get it explained...

Having to explain it, clear up misunderstandings or seeing participants overlook almost an entire page of new bids (browser error?) while updating the highest bids table + current auction termination upto 3x per Minute (!) is a worst-case scenario and hurts everyone.

Of course I could make the Auction EBay style, but that means everyone will try to "snipe" their items last minute. People with less potent internet connection would definitely lose out and we'd have losing bids due to smallest time syncronization problems (just see how important it is to get people synced onto the right time zone and you see what trouble we'll run into when it comes to synchronizing onto 1 Second).
I really hardly see such auctions in Forums for exactly these reasons, except when I can't be around to manage the final minutes, which I try to avoid.

Another way I've seen was to make the auctions either open end (seller can at any time agree to a price suggestion, often leaving other people pissed getting into the auction too late), and last but not least the "buy it now"-Model. That doesn't work for me, since I can hardly assess a reasonable value for many of the cards I sell. Often enough, those that I assume would spark alot of interest fail at 1-2 Euro, cards that I assume are "generic" rocket upto beyond 100 Euro (?).

At least that's my perspective.

Bottom line :
Having the first posting open in a separate Tab and hitting refresh once every Minute can't be too much to ask, works for 50MBit connected users just as fine as for 56k Analog Users.
That's as convinient as it gets and people don't even have to monitor every individual posting, even so they have at least ~3 Minutes to check on their item and consider increasing their bid or not. Honestly, IMHO doesn't get any better than this, while keeping fair play for all. At least I don't know of any way to further improve that auction technique.

(for those that mind the high sales prices reached, bare in mind that is usually nothing compared to the bidding wars I went through to aquire many of them - and I bet you have never seen me moaning about it )

Next time I will make the 2nd Posting an explanation Post concerning the +5 Minutes rule. That should keep everyone up to speed

Since we have a Voting function in the Forum, I'll start a Poll about the most desired Auction technique. Having the majority decide about what they like best is probably the smartest solution and I'll then make my auctions that way.
