Laura, I'm glad to hear that it's working. When I used it for my RB Pepper,I just had it filled at my local pharmacy. I'm sure that Walmart,Target,Costco if you have one, or Sam's would be a lot less expensive to have it filled there. Just go to your vet and have him fill out a prescription for Giz and then you should be able to go any where and save money too. Good luck.
