What is a good item to sell on-line and who do you sell it to?

A good item to sell online is eco-friendly products, such as reusable straws or biodegradable phone cases. These items appeal to environmentally conscious consumers who prioritize sustainability in their purchasing decisions. Targeting millennials and Gen Z, who are particularly invested in reducing their carbon footprint, can enhance sales and brand loyalty. Marketing through social media platforms can effectively reach this audience.
