Loads of bells
You first need mail paper and any item or fruit. Write a letter that you can read Something like "hello how are you doing" not like " " then send it with a present like fruit really send it with fruit because theyl probably give you rare fruit 85% of chance then it will go down like to 15% well so then plant the "rare" fruit.
When it grows plant it again and again and again until you have uncountable trees of rare fruit then start selling it to nook this works I did it about a million times now I get about 100,000 bells each time fruit grows you can also do the mail thingy with furniture....
They normally give you more furniture once I got a Moon an other time a white katana. This didn't happen by mail but bottle mail some sort of idiot called Ore-X gave me once a gold axe and an other a gold slingshot... What an idiot!
Hope it helps!
