I was hesitant as first after reading warnings online about buying from overseas sellers so I called and spoke to Sean, who was competent and reassuring. Still cautious since one of my dogs only weighs 4 lbs and bad/wrong meds (in my case Revolution flea/tick) could be fatal, I ordered. Although it does take a while, they do tell you it does, the product was exactly what I got from my vet here in the states, within plenty of exp. date and my dogs are fine. Great product and service. Thanks!
