Animal Crossing: City Folk Tips

More Bag Space
Give yourself more bag space by writing letters to yourself, but not sending them. You can then put items up there like fruit, furniture, and your tools while walking around town. When you get to Nook's, remove the items from the letters and sell what you want. I personally use 9 which allows for easy fruit gathering with 15 slots in the bags, but you can use however many you want. Letters are so cheap that if I get a lot of mail I throw them away so I can read my mail, then buy new ones, but most times, I'll just read my mail one at a time.

This allows me to bring in 3 more trees at a time and when I'm harvesting non-native fruit, that's 500 bells a pop allowing for much faster fruit harvesting!
