It's called anchoring, and I suggest all auction bidders read up on it. It's really interesting. From Wikipedia:
"Anchoring or focalism is a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information offered (the "anchor") when making decisions. During decision making, anchoring occurs when individuals use an initial piece of information to make subsequent judgments. Once an anchor is set, other judgments are made by adjusting away from that anchor, and there is a bias toward interpreting other information around the anchor. For example, the initial price offered for a used car sets the standard for the rest of the negotiations, so that prices lower than the initial price seem more reasonable even if they are still higher than what the car is really worth."
Auction houses do the same thing by hiding the BP away from the bid price. The bid price is the "anchor." The BP is irrationally adjusted away. And then the AH immediately flips their numbers to include the BP when they're promoting how big their sales are. It's so obvious why they do that I frankly find it "absurd" that you think all customers treat a straight combined bid/BP number (ebay format) the same as one which hides the ball/BP in their Auction Rules page. Auctions are impulse buy markets, where people are not making the most rationale buying decisions to begin with. It only takes one irrationale participant to drive a price up.
If you make people do multiplication in their heads in a 20-minute extended bidding period at 2am, you will get irrational behavior. That's why you see 19.5% BPs instead of 20%. It makes it less palatable to do the actual math. Quick -- what's 1.195 x $1,900? Most bidders know their number will bring them over $2,000, but some won't realize or care that it's $2,270.50 until they get the invoice. Others will do the 20% calculation in their heads to get to $2,280 and then take an irrational discount in their heads to account for the 0.5% discount, which "saved" them all of $9.50 on a $2,000+ purchase.
Again, it's a form of anchoring, which is a very common way to set prices. E.g., $19.99 seems like way less than $20 to most in TV ads.
