Well we all know if u try to seel the fruit that was in ur town when u got there
would only get 100 bells.So an easy way of making money is to write letters to ur town folk and send them the fruit that was in ur town when u got there 90% of the time they will send u a different fruit back like ORanges, Appels, Cherrys, pears,Peaches,Coconuts u can sell these for 500 bells each or plant them and they wil grow in to rare fruit tree and u can sell the fruit on it everyday
Hope this helped u Please rate!
