Apparently we owe our modern idea of pricing goods in shops to the Quakers. Before that nothing had a price and it was all done by haggling rather like that scene with the beard on the market stall in "The Life of Brian" - the Quaker idea was that everything had a fair price, and their shops became very popular because of this resulting in other shops adopting the system.

Try to imagine the scenes at the Tesco checkout if the Quakers hadn't bequeated us this.
