I love Pet Bucket for my dog's flea tick treatments. I plan a month in advance to allow for shipping time (usually 2 weeks) and then put it on auto ship. I never have a problem. I always check the expiration date and it's always way in advance of when I receive them. there's never any trouble with the quality of the medications. I think mentions of this in other reviews could be trolls or competitors. I've never had any issues. I like protecting my dog's health at a savings.
