Query: very quick delivery

I have ordered this item many times from various dealers. This was by far the quickest I ever received the delivery. As for the product, It is as good or better than other brands such as Sonovi. My dog has been taking them for 6 years. He is almost 10 yo and 116#. He still plays like he's a puppy with pretty good mobility.
