I am very disappointed with Amazon selling policies, because I find many dishonest and crooked vendors on there. For example, they advertise as they guarantee returns and refunds, when in fact if you try to return something, you get a message “this item is NOT eligible for return”. This refers to dog’s treats and supplements. Once I received a very stale dog’s treats and another time a completely EXPIRED supplements at a full price. You cannot even address such issue to Amazon. There is even no way to contact them about it! Another big problem is that some vendors apologize for a defected products and promise a refund, but indeed NEVER refund you the money! Make sure you don’t forget to follow up on your refunds. I last my money twice because I didn’t check on time.
