Auctions are ordered by price, then by time with newest coming first within a given price point.
Auction visitors tend to find a quantity and price point they want and then pick the first one.
This means that an auction for an item at a given pr/qty can get "pushed down the stack" by the addition of other auctions at that very same pr/qty. While not horribly unfair, it is sorta unfair.
Eg. 100 cherries at 200c. Assume I add 5 auctions like that. someone can come along a few minutes later and add 5 or 10 more auctions for 100 cherries at 200c and their auctions will be the first ones that shoppers see, and probably select.
Fixing that should make for some interesting SQL. Thanks for reading this.
