There is free competition. You can put up a website advertising your items for sale for near zero cost and anyone in the world has the ability to see it. You can also list it for sale for free on Facebook marketplace, or Craigslist, or staple a paper to a utility pole near your house.

It’s much free-r than it used to be, when the paper on a pole and paying for a newspaper ad was the only option.
