Flea Market

The Flea Market is a weekend event where villagers from your town allow others to come in and buy some of their items, although some of their furniture isn't for sale for various reasons. Many animals choose to sale items at a raised amount.

The player can also sell his or her own belongings - any furniture out on your ground floor when villagers visit is up for sale. However, even if the player runs out of items to sell, the villager will take a few minutes to leave unless the player leaves, ni which case they'll ask if the player needs to go, and say they should leave. If he or she leaves and re-enters the house enough, every villager will come in once.

Items or creatures that a villager buys from your house usually will be displayed in their house the next day.

Flea Markets are held usually on Saturdays, but if the player is ahead of a scheduled flea market (due to a time-warp) if you time-warp back in time the flea market will be set to the next day (like a lot of other events).

When you are buying from your neighbors you can either take the price they give you, or leave it. If one of them is buying from you however, they will haggle by saying the price is too high, and you have to lower it for them to buy it. Comically a cranky villager, when buying something from you, may hand you money that they claim is from their super secret giant bell hoard.

A villager will buy a max of three items from your house. However, if the player goes into a different room without leaving the house, then go back to where the villager is, it resets it so that the villager will buy another three items. This can be repeated at the player's discretion. The maximum acceptable price they will pay is a little over twice the selling price to Tom Nook, which means for furniture, they will sell for half the buying cost. If the player has bugs or insects in the house, the same rule applies, twice the selling price. So if you stock up on high priced fish/insects before or during a Flea Market Day, the player can make double amount of bells by placing them in the home and coaxing the villagers towards the creature you wish to sell.
