One of the ones I can remember is someone attempting to sell 1 crafted Crescent Moon Chair for 100 NMTs. Also someone attempting to charge 20 NMTs per entry fee at a 600+ price turnip island.
I made a deal to purchase his poster and a hip wrap shirt given to someone by him for 30 NMTS. I've decided to start a Raymond museum, where everything will be displayed beautifully on gemini tables. Bookshelves will surround the priceless artifacts, detailing on the history and controversy of the lore over the office cat.
Once you've obtained it you should put it on display behind some iron bars and charge people 99k to visit and look at it.
That's honestly ok because I didn't know the economy when I first started out and was ready to pay 20 NMTS for one crescent moon chair and I had to provide the materialsI low key ripped someone off back when the game first came out.
They offered me a cherry blossom DIY in exchange for one of my super common DIYs. I didn’t question it, and they seemed happy with the trade, so it’s all good I guess.
