Auction houses will never do anything that loses them money ... that's why they have zero transparency, why they give you no financial recourse if an item is delivered not as described, and why they do the 15 minute rule for extended bidding.

You're all lucky they don't change that to the 30 minute rule. The longer people have to bid the more opportunities they have to make money.

If the auction houses really wanted to help the collector they'd do away with the extended bidding all together, and end things at a scheduled time, as is done on ebay.
