If you decide to request a refund within the 90-day guarantee window, who covers the return shipping is worth confirming directly.
Contact customer support to confirm whether return shipping is covered by the brand or paid by the customer, since this specific detail isn't always published on the pages we reviewed.
A guarantee that requires you to pay return shipping is worth less than one that doesn't — worth confirming this detail before you order, not after you've decided to request a refund.
The 6-bottle pack is the lowest price per bottle, backed by a full 90-day guarantee.
