Ok this might be the most working and its not a cheat here are the steps
step 1. buy mystery boxes (cheap,regular,expensive...)
step 2. open it (put it in your home and let your pet open it)
step 3. get item (depends on what kind of box you got)
step 4. sell it (sometimes it doesnt cost more than the price of the mystery box but alote
of times your lucky and get it theres a 40% chance you dont get a good item 45% chance
youll get x2 or x3 of how much you bought it for and a 25% chance youll get x5 and up)
step 5. repeat until you have alote of money then buy plants
step 6. wait for plants to grow in your garden and sell the grown item (youll get around
50+ profit depending on the size and plant)
