Unfortunately, due to technical limitations, we cannot issue a refund for a product that was purchased over 90 days ago. However, we want what’s best for you and here at Mend, we can exchange your product to any other MEND product even if it's older than 90 days as long as the product seal is not broken and is in resalable condition. In cases like this, please email us with Subject “Returning old product” to support@mend.me and include your name, email associated with the purchase and your 4 digit order number.
