Reducing Amazon selling costs can help you protect your profit margin. Start by checking where most of your money is going.

Choose the right fulfillment method for your products. Avoid sending too much inventory to FBA, especially if products sell slowly. Review your advertising campaigns and reduce spending on ads that do not generate enough sales.

You can also look at product size and packaging. Smaller and lighter products may help reduce fulfillment costs.
