Hot Tips
- don't bother crafting items with gold nuggets. their value doesn't increase when crafted
- don't sell items crafted with non-native fruits. the fruit is worth more.
- Items crafted with your native fruit do sell for more, but not as much as selling on another island

More Hot Tips
- buy materials from nookazon for more than Timmy and Tommy offer. Ex: T&T buy giant clams for 900 bells each. Buy them from another user for 1000-1500 and both of you will profit
- only sell shells to get nook miles! otherwise, save them for crafting

shell partition

ABOUT FRUIT ITEMS
- both these rugs sell for the same amount: 1,200 bells
- cherries are native to my island and sell for 100 bells each, while oranges sell for 500 each
- you profit double by crafting with the native fruit, but make less with non-native fruits
