I purchased Stronghold for my animals from Pet Bucket and I have to say they have the best prices on the only flea and tick treatment that works for my little ones. Mind you I have three dogs and six indoor/outdoor cats, and we live in NC where the fleas are mutated or something as nothing kills them - well except for Stronghold. I like that Petbucket does not charge an arm and a leg for the product as I would be bankrupt in no time with the animals I have. Shipping times are not the greatest, but this is no fault of Pet Bucket. The items come through customs and get stuck. My last order was placed on 3/17 and I received the product on 4/8, so make sure to leave yourself enough time for delivery before the next treatment. I had tracking on the package and saw that it left the point of origin fairly quickly, but got held at customs for quite a while before it was finally released to USPS. I also set up an account for auto-ship in three months, but I cannot comment on the wait time yet as I just set the auto-refill the last time i ordered.
