Costco denied to honor my good RX for my pets medication of phenobarbital. We had gotten it there before many times with the good RX and now they say that good RX no longer will allow medication for pets with the Good RX card . Please tell why is this ? It's the same medication So I don't understand why good RX would not honor they prescription. Otherwise I assume it's just Costco not honoring the good RX card. My question is do you honor prescriptions for pets or not.If so I will just change where I get my prescriptions from now on. Thank you for your time and I hope to hear from you soon. Gena Steele
