The wonderful Petbucket folks are the BEST EVER to deal with - kind, compassionate, understanding and always flexible!
A unidentified mail clerk at my US Post Office literally HID my mail from Nov 2018 until Jan 2019 - my recurrent order for my Cocker Spaniel's heartworm Rx was in the hostage mail. Petbucket replaced the order immediately upon notice of missing Rx meds!!
