We stand behind the products we sell. We guarantee that the product you will receive will be the product you ordered (no counterfiets or substitutions!), will arrive in good useable condition. We will even give you a refund if you simply change your mind and decide you no longer want the product before you use it (product must be returned un-opened and in saleable condition). Simply contact us at info@canadavet.com for details on how to receive your replacement or refund.
