I’ve made a few interesting friends through buying & selling consumer goods on Craigslist.
The market is simple.
It consists of buyers and sellers transacting goods and services.
Sellers want to sell for the highest price.
Buyers will haggle for the lowest price.
If the price is debatable, after several minutes of negotiation, the transaction is done.
Then it’s off to conversations and a firm handshake.
Craigslist is a classic example of the free market.
Buy and sell as you wish, without coercion and regulation.
But be prepared to deal with frauds, flakes, and liars.
