If your damaged item is a current pattern (it's available for purchase at Lupinepet.com) the least expensive way is for you to submit a guarantee replacement form on Lupine's website by clicking on this link. Lupine will have you submit a photograph of the damage and then ship you the replacement item at no cost to you.
If the item that is damaged is a retired pattern and I have the item on my website, purchase the item from my website, and mail back the damaged item to me:
Pet Expectations P.O. Box 51 Hooper, Utah 84315-0051
Once I receive the damaged item I will refund the purchase price on the order you placed.
