how to sell a product online for free is a common query for those looking to start an e-commerce business with minimal upfront costs. On Amazon, you can sell items without paying any monthly fees by choosing the Individual Seller plan, where you pay $0.99 per item sold. However, you’ll still need to pay Amazon’s referral and closing fees for each sale. If you’re looking to minimize costs further, you can start by selling used items or drop shipping, where you only pay for products when you make a sale.
