If you are getting 20–25% profit through online arbitrage and wholesale, then that is a good profit margin. You can go with these products. Because Amazon fees are really high these days, maybe when you have estimated the profit margin, it would be 25%, and at the end, after deduction of fees, you get 10 to 15%. So, high-profit margin products should be selected so you can get at least 15 to 20% profit margin.
