Manufacturer websites – Companies like Bayer (Advantage, Frontline) and Merck (Revolution) sell products directly to consumers in regions where online sales are permitted.
When selecting a source, verify that the product is approved for the specific species and weight class of the pet. Some formulations require a veterinary prescription; these are unavailable at general retailers. Check expiration dates and ensure the packaging is intact to avoid reduced efficacy. Shipping restrictions may apply to certain chemicals, so confirm that the chosen vendor can deliver to the intended address.
