How to avoid problems with sports nutrition delivery from online stores?

Hi! Have you ever had any issues with delivery of orders from online sports nutrition stores? I've heard stories of packages taking a long time to arrive, getting lost, or arriving damaged. How do you choose a store to minimize these risks? Do you pay attention to shipping methods, packaging, or return policies? And if the product arrives in less-than-perfect condition, how easy is it to get a refund or exchange? It would be helpful to hear your real-life experiences so I know what to look for when ordering.
