The ReSonix Program

Reduce, Reuse, ReSonix

As you know, Sonix phone cases are built to last. In fact, they’re made to last past the next iPhone launch. So what do you do with your case when it’s time to upgrade?

We're proud to introduce the ReSonix program - created to encourage the reduction of waste, while giving our loyal customers an incentive to donate pre-loved cases for a second life.

1.) Donate your pre-loved case (in good, usable condition) to a local Goodwill, Salvation Army or any charitable non-profit organization.
2.) Take a photo of the case and the receipt for the donation and send it to
3.) Our support team will send you a one-time use discount code for 30% off your next case purchase. 


  • Each donation receipt will receive ONE promo code for a ONE time case purchase per customer
  • Two donation receipts will be accepted throughout the year. A new code will be generated every 6 months starting 1/27/20.
  • Code applies to one phone case only. However, other items may be in the cart to qualify for free shipping.
  • Cannot be combined with other offers and discounts
  • Donation receipt must be from 1/27/20 and on (donations prior to 1/27/20 will not be accepted.
