Depending on what customers purchase, the prices will rise or fall.
“It’s an ever-evolving happy hour,” Flora said.
The prices will never go higher than around 10 percent the base cost, but will drop to as much as 50 percent below base cost.
For example, a Bell’s Two-Hearted Ale may be $3 normally.
But, depending on the “market” activity (i.e. patrons buying tendencies) it could be as much as $3.25 or as little as $1.50 (prices fluctuate in increments of 25 cents).
The prices will change every 15 minutes and there will be, at random, a “stock market crash” – signified by air horns – when all 28 beers are sold at a low rate for five minutes.
