Brand Protection continues to be of the utmost importance for our company and our customers. We’ve spent the last several years building and rolling out processes to that end.
With that in mind, effective immediately, we’ve added Amazon to our Do Not Sell list.
Please make sure you frequently review the Authorized and Unauthorized Sellers on below to ensure your adherence to our Brand Protection Program. Selling to an Unauthorized Seller violates that program.
If you have any questions concerning selling online, please contact your relationship manager at 800.898.0705.
Thank you for your partnership and continued support of the SuperSprings International brand.
