The art of haggling over prices has largely been lost at the grassroots level and it is a great pity
Back in the good old days there were many small shops and markets which were directly owned by the person sitting there, and you could haggle prices with them. In my opinion, this was a fine art. One employed multiple tactics such as:
a) Calibrating to meet in the middle - they are charging 20, you are willing to pay 15, so you say 10, they say 18, you say 12, and in the end the difference is split.
b) Appeal to emotion - hey boss I've been an old and faithful customer of yours; come on don't I get a loyalty discount?
c) Business sense - how about if I buy more, can I get a bulk discount?
Nowadays everything is dominated by supermarkets and chain stores and of course we can't haggle prices with the employees - the prices are fixed. I do believe that the loss of this skill is detrimental to us in our careers and daily life because the art of healthily bargaining is not sufficiently practiced enough.
Currently, our first haggle tends to be at our first salary negotiation, first used car bought or first house purchase. The lack of prior practice does not build up enough skill for these crucial moments.
