You are receiving these bottles at cost. This is a special promotion shipping bottles that have leaked or may leak. The product is fine and safe. Please notice when you receive the bottles, they will be labeled with a sticker that either says “Stained” or “Unstained” on the bags they are in. We need to determine if any bottles leak in transit and need your help determining this. So please inspect each bottle and let us know the result. Any new staining or obvious liquid should be reported to us. Thank you for your help in this.
