The Item Duping Glitch
This glitch requires a placeable item, a placeable surface, and a local friend (or a dummy account and a second controller). Note that a placeable item is specifically something you can place as a piece of furniture, not just an item you can drop.
First, put down your placeable surface. These are things like a cardboard box or table. Then, put an expensive placeable item on top of the surface. Put your local friend on one side of the surface while you stand on the other side.
Here’s what you must do. Have your friend rotate the surface with the placeable item on it. Then, in the middle of the rotation animation press the Y button to take the item off the surface. If you do this right, you will pocket a copy of the item while the item itself stays on the surface. There you go! Infinite items.
There’s really no risk to using this glitch. If you press the Y button too soon or too late then you will simply pocket the item as normal. Just place it back on the surface and try again.
You can, of course, do this with Tommy and Timmy Nook’s “hot items” to make a lot of money, but the most effective way to make money is given to you right at the beginning of the game. You start with a cardboard box and a Nintendo Switch. The Nintendo Switch is one of the highest value items the game has to offer. Dupe it a bunch of times and sell them off and soon you will be a millionaire.
