1800PetMeds

Convenience is king to PetMed Express, which bills itself as America's largest pet pharmacy. Through 1-800-PetMeds and 1800petmeds.com, as well as a catalog with hundreds of items, PetMed Express offers prescription and nonprescription medicines and other pet care supplies for your calico, collie, or colt. Founded in 1996, the company purchases its products at wholesale prices and ships directly to customers. Nonprescription medicines, such as flea and tick medications and health and nutritional supplements, account for about 60% of PetMed's total sales. The company makes the majority of its sales via its website. It also offers pet health information on a separate site, PetHealth101.com, which it sponsors.
