Profitability of goods

Hi, it seems that the profitability of goods should be reviewed, because it does not seem very profitable to open a Fast Food Restaurant/Jewelry Store business… The picture shows the names of goods, their cost in importers and the price for which they are sold to customers.


I really noticed this on the Jewelry store.
it’s really hard to make it profitable.
and not to mention the marketing, the marketing expensive would make it impossible to get it profitable.

I noticed that the larger the range of products, the more purchases 1 customer makes. The clothing store is too cool.
