I ordered 6 bags of CET chews for my dog. I consider the CET brand to be far superior over Ora-clens that I've used in the past.
When I received my order, I found only Ora-Clens chews with a note saying they had been substituted for the CET chews! I called customer service and was told I could ship them back or be refunded 15% of the purchase price. I was almost out of chews which are used daily) so I chose the 15%.
Soon after, I checked the price for Ora-clens chews on Amazon. They were $2 per bag cheaper even after figuring in my refund!
Apparently, CET chews are scarce right now. Other companies are stating that they are "back ordered" or "out of stock". Entirely Pets says nothing on their website; they just send you junk instead of what you ordered.
