ProstaVitalis is advertised with a 60-day money-back guarantee. However, there is an important discrepancy between two of the brand's own pages that you should know about before ordering.
The sales page states: "a full 60-day, no-questions-asked money-back guarantee… We'll refund every cent. No returning the bottles. No paperwork. No hassle."
The brand's separate Shipping Policy, under its "Returns" section, requires:
Per that same policy: "failure to return all bottles will result in a partial refund," not the full refund the sales page promises.
Email support@prostavitalis.com and ask them to confirm, in writing, whether bottles must be returned for a full refund and who pays return shipping. Save that confirmation along with your order confirmation email.
Note: the Refund Policy and Terms pages list +1 (970) 406-7582, while the Contact page and sales page list +1 (720) 619-8477. We recommend starting with email to get things in writing.
