I am offering up to 10 reorderable AC:NH items from
this list to whoever can help successfully lead me to someone actually selling a yellow rose TBT collectible
I also have most of the reorderable items from AC:NL if you are more into that game.
If you're more of a Pokemon fan, perhaps I can instead help you catch the shiny Pokemon of your dreams or give you an item of your choosing within reason. I have at least one Pokemon game from each gen including Brilliant Diamond, though I have not reached the endgame yet for some of them.
Of course, if you have a yellow rose collectible you can sell me, I'd be more than happy to pay for it using in-game or belltreeforums resources.
