Comment History of Posted Prices (Score 1) 155
Until the 18th Century there was no such thing as "posted prices", unless prices were set by government regulation (only certain staples, and rarely). Instead you always had to dicker with the seller to arrive at what you would pay.
In the mid 1700s Quakers in Pennsylvania decided they did not like dickering since it meant both parties were trying to deceive the other to their best advantage. It also meant bad will if person A found out he paid more than person B for the same goods. To eliminate this troubling daily moral dilemma they introduced the startling new idea of offering goods at fixed prices that were posted for all to see.
Oh, how not 21st Century can you get? The idea of prices being fair and equitable, and honestly posted for everyone! How quaint! Our corporate masters have decide that we all techno-rubes to be fleeced as efficiently as data harvesting and AI can make it!
