it makes sense for some people to do this. They would buy all five boxes if they got it at a certain price. I would buy five boxes of puros indios for $20 each. They seldom end up winning all five for at a certain price, and at a highter price they don't want all five, maybe then they will enter a new bid to get two boxes. And logically if you think about it, it really has no effect on the final price of the lot, especially if they are outbid, their bid becomes irrelevant. They would be better off in fact not bidding on the lot until the auction is near closing, for if they bid early, other bidders all week will be pecking away at it driving up the price, if they wait, and the bidding is still low enough worthy to buy five boxes, then do it.
