Chewy did the same thing in our situation. Our Heidi had to be on a liver medication for the last couple years of her life. When we lost her we had just purchased a refill of the medication. My wife called them to see if we could send it back as we hadn't used any of it yet and they did the same for us, credited us back and told us to donate the medicine. We've been purchasing from Chewy for several years now and they are a great company to deal with.
