If the RESPeRATE coupon code isn't working, try the following steps:
- Check the expiration date of the coupon code.
- Ensure the code is entered correctly, without any typos.
- Verify the terms and conditions of the coupon to ensure it applies to the items in the cart.
- Clear the browser cache and cookies, then try again.
- Use a different browser or device to see if the issue persists.
- Contact RESPeRATE customer support for assistance.
If none of these steps work, the code may no longer be valid.
