Where do you get bells?

If you're talking about Bells in the Animal Crossing games, then here are ways of getting Bells.

  • Catch bugs and fish and sell them to Re-Tail (New Leaf only) or the Nook's store
  • Shake every tree in the town (some trees will drop 100 Bells or a furniture item that you can sell)
  • Check the Bell rock (everyday there is a rock to hit with a shovel and Bells come out of it)
  • Exchange fruits with other players and plant them in your town(each fruit sells for 500 Bells)
  • Sell furniture that you don't need

If you aren't talking about Animal Crossing, then I can't help you
