Think everyone is talking about throwing away dud tickets if they don't want like 5 dozen sparklers.Why would you throw away your items instead of selling them.
You can also throw away rotten turnips/fruit and junk you fish out of the river/lake/ocean thus saving you the fee Reese charges for disposing of that stuff.
Also if anyone wants, I have like 4 Ultra Hands, 2 Ultra Machines, A Boxed Figurine, Ten Billion Barrel and Lovely Phone left at the end of the night here. If anyone needs any of that, let me know.
