Problem: When a person wants to buy 1 of something, rather than a large stack, if there are many large stacks for sale at a cheap price, only so many are shown. The rest will not be shown until those sell.
So a person wanting to buy a smaller quantity can't unless there are fewer than max_page number of auctions shown.
Example: Allspice, often sold in 250 lots. If I want to buy 5 of them, I can't, because the smallest lot shown is 10 (and listed for a slightly cheaper price than a 5stack which isn't shown). This can impact newcomers greatly, because they are less likely to be able to afford a larger stack, and they may only need a few.
