- Weight-based shipping rates are calculated based on the total weight of the items in your order. The heavier your package, the higher the shipping cost due to increased handling and transportation requirements.
We understand that shipping costs can sometimes feel high, and we want to be transparent. Our company does not profit from shipping fees. Instead, these charges directly reflect the costs we incur from shipping carriers to deliver your order safely and efficiently to your doorstep. We regularly review our shipping rates to ensure they remain fair and competitive.
If you ever have questions or concerns, feel free to reach out to customerservice@clsi.org — we value your understanding and support!
