When I saw the listings I wondered if it was too good to be true. Yet, trying to save money I took the bait. Sure enough, it was nothing but water. I've been buying flea meds for years and know the smell when I smell it. I even tested it on my finger, it was just water. Great job on the packaging but it was counterfeit. I reported it to eBay and filed a report directly off the listing. Ebay responded by saying that they could not find the listing! What other channels do we have to stop these scammers before our pets get sick?
