Jumble sale

El Jumble sale (Flea Market in English) is an event of the Town in which you can sell what you do not need to the neighbors, who will come to see you if you are at your house to buy. You can also go into other neighbors' houses and buy things from them (if you don't want to sell anything, don't go into your house or stay in it, but if someone comes in, you go out and come back in).

Held on the first Saturday of each month (except January and August) in Animal Crossing: Wild World and Animal Crossing: City Folk / Let's Go To The City are held on the fourth Sunday of each month unless there is another event that Take away, for example, the August Fireworks.

Sometimes you will be able to sell things more expensive than in Tom Nook's store. In addition, if you put Giroides in your house, your neighbors (if they want it) can buy it from you up to double what it would normally cost.

Keep in mind that many of the objects will not be bought from you, such as fruit or paintings and costumes created by you.

The bugs and fish that you buy from the houses of your neighbors, you can donate them to the museum but nevertheless they will not appear in your registry (since technically you have not captured them).

Tricks

• If you are at home and you do not want to sell anything, do not talk to the neighbor who has entered, and that way he will not move from the door. The problem is that if you want to move furniture, you will not be able to because you have a visitor (just as if someone came to your Town and entered your house) and then you will have to leave for the neighbor to leave.
• If you want to remove the objects from the central room to exchange them for ones you don't want, open the Gate. Thus, everyone will be at home. When you're done, close the gate.
• When you manage to catch a high value fish (for example, one of 15.000 Berries) you will sell it at your house, if you want you can get double the value for a fish of 15.000 Berries (30.000 Berries). Although in living beings, this equivalence is not very strict, and, for example, you can sell a Red Snapper of 3000 Berries for 10.000 Berries.
• You can also earn lots of berries by selling shells, flowers, and furniture that you find in the trash can or lost property. Take into account what its price is and try to double it, and even triple it.
• The sales limit is 3 for each neighbor, but if you go to another room this "restarts" and you can sell another 3.
• If you turn off the light, the neighbors will believe that you are not there and so you can arrange things to sell.

Glitch

In Animal Crossing: Wild World, as in the other games, it is necessary to leave the house so that the neighbor who tries to buy you something leaves. However, if you walk very slowly towards the door, when he says Are you leaving? Well, nothing, I have to go out ... run inside the house. You will see how sometimes you will not leave automatically, but you will stay inside the house.

Animal Crossing: New Leaf

In this game he does not appear, being replaced by being able to sell the furniture and others in Recycling Equipment.
