Great price, awesome sellers. Simparica works better than Nexgard in my opinion...plus from what I researched online that it tapers off, where nexgard just kinda ends. Dont be afraid to try Simparica even though it is not as popular as the nexgard :)
Excellent product, excellent price and no prescription required. Any questions or concerns get an immediate response. Do allow extra time for shipment, but it is totally worth the wait. I would recommend the product and Sierra. They really go above and beyond; excellent customer service.
