In ACNH, if you are good enough at the Turnip market, then you even have the chance to make a lot of ACNH Bells, which is high yield, but also high risk. Stalk Market is a volatile market where Turnip prices go up and down. Typically, Turnip sells for between 50-150 Bells, but they can also be worth as low as 15 Bells and as high as 650 Bells. MMOWTS will give some tips allowing you to get as many Bells as possible by selling Turnips.
When does Daisy show up?
Considering that Daisy Mae sells her Turnips between 90-110 Bells, then you need to be careful when buying Turnips. Turnips bought at 90 Bells can make you more money, and Turnips bought at 110 Bells can bring you to financial ruin.
Daisy Mae will show up on your island every Sunday and stay on your island from 5 am to 11:59 am, but she'll stay longer if you don't go inside. You can go find her, and once located, she'll sell you Turnips in bulks of 10. The threshold to enter the Stalk Market is at least 900 Bells, and you have to buy 10 at a time.
Turnips have a lifespan of only a week and you have to sell them within a week. You can sell Turnips to Timmy and Tommy every day other than Sunday. You can log in to the game around 11:50 am to see Timmy and Tommy's valuation and see if that day's value is worth selling or not.
If you want to avoid Stalk Market risks, you can use the Turnip Calculator, which estimates the price of turnips in the morning and afternoon for each day of the week. You just need to input the Turnip prices and the Turnip price for each subsequent day. Typically, when you enter the prices for Tuesday morning, the price of Turnips for the rest of the week can be determined with nearly 100% accuracy. Turnip Calculator can help you make as much profit as possible.
Of course, if you don't want to take any risks, you can go directly to MMOWTS to buy Animal Crossing Bells, which is also the fastest way to get bells and can make you a millionaire in no time.
