Where can one purchase pet accessories?

Pet supplies are available at a wide array of websites. One can purchase through major pet store websites, such as Petco, or major discount stores such as Target. There are also sites that carry medications and flea preparations such as Pet Meds. As always, Amazon is also an Excellent source, as they carry everything under the sun. As to which source is the best, that is a subjective decision, and dependent upon what one is shopping for.
