4. Not reviewing supplier's policies: Before partnering with an Amazon FBA supplier, it is essential to review their policies, such as shipping, returns, and warranties, to ensure that they align with your business's needs and expectations.

5. Overlooking communication: Communication is essential in any business relationship, and it is vital to ensure that your supplier is responsive and communicates clearly and effectively.

6. Not visiting supplier's facilities: Visiting your supplier's facilities can provide valuable insights into their operations, quality control processes, and overall reliability.

7. Rushing the selection process: Finally, rushing the supplier selection process can lead to poor decisions and costly mistakes. Taking the time to research and evaluate potential suppliers can help ensure that you choose the right partner for your business.

By avoiding these common mistakes when selecting an Amazon FBA supplier, businesses can partner with a reliable and reputable supplier that can meet their needs and ensure their success in the e-commerce marketplace.
