After your initial membership term is complete, your credit card (sorry, we cannot accept debit cards at this time) will be billed the same rate you joined and you’ll continue to receive all of the benefits of HSI membership without interruption. There is no obligation; you can cancel at any time to get a full refund for the current 12-month term. If you have any additional questions, please click here to contact our customer service team.
