Put yourself in their shoes...
If you advertised the "normal" auction price of cigar X at 50 dollars over the last 3 months with the high at Y and the low at Z, then you would be shooting yourself in the Xick... This place pays their salary on the higher bidders and on the average and above average bidders. Not on the low bidders... You can create an app that watches the cigars you want by putting them on your watch list, and then checking them after they sell.
It's like going to Vegas. How do you think they built all of those hotels?
