VetShopOnline.com review: Pfizer does not sell to this company

I ordered Revolution for my dog, and was suspicious upon receiving the product so contacted Pfizer Australia (the manufacturer of the product) to confirm that the product was in fact sold by them to vetshoponline. Not only did Pfizer Australia confirm that they do not supply this product to vetshoponline, but they also confirmed that the batch number listed on the package was for a different dosage than what I received & was marked on the package - this product was not produced by Pfizer. When I emailed vetshoponline about this, they claimed it was a real product obtained directly from Pfizer and I could pay for shipping back to Australia if I wanted a refund. Given their track record of selling fake product, I will now have to send this product back via courier to confirm delivery, which is very expensive, and the company will of course not pay to return it as it is worthless. Buyer beware - this product is FAKE - Pfizer does not sell to this company!
