How do you get free bels on animal crossing

There is no way to get free bells. Ways to get bells are to sell some of your fruit on your trees to Tom Nook. He will pay 100 bells for each peice of fruit. If you go to somone else's town using DS to DS or WiFi, and you get somone else's fruit, Tom Nook will pay 500 bells for each piece. If you go near your beack there will be shells. Pick them up and sell them. Different shells sell for different prices. Pearl Oysters sell for more than 1,000 bells, as others might not sell for more than 200 bells. Hope this helped you to earn more money.
