It has been said time and time again that the best way to become a NeoMillionaire is through restock and then selling at your shop. True! But not completely. One can only buy a limited quantity of items through restocks. After your shop is size 30, you probably are having a difficult time with fully restocking your shop if you put your items on the shelves right after restocks.
So what do I do? I make my shop sell similar items. I prefer selling plushies. There are many collectors out there and don’t really mind buying plushies which are a little bit overpriced. Just don’t overdo it of course.
