I have been using Petbucket.com for about 2-3 years now. I have really enjoyed the service. I order one of the most hard to find and costly dog flea/ticket/heartworm combos that is very costly locally. I have never had a problem and also order for my daughter and cousin. They also love the product. I would only ask for 1 slight improvement: other companies that I deal with give automatically tracking updates for free. Other than that, this service cannot be beat.
