To be honest I was concerned about ordering from a company that I'd never heard of before. I charged my credit card nearly $200 on 5/11/2023 for Simparica Trio for 12 doses that would have cost me $360 from my local vet. I was pleasantly surprised that I received my dog's meds in just 11 days from the UK. They look authentic with the same packaging I normally get so I'm feeling like I made a smart decision by purchasing from this company.
