I used to buy Nutrimalt from my local pet store for $7.50 per tube, she went out of business and I found it on Amazon for only $3.19 but wait, once I had ordered 2 tubes of it the shipping and taxes combined cost me another $12+ now who in their right mind is going to purchase under $7 worth of product and end up paying thru the nose for it in shipping and taxes. I even ordered other items over $25 thru Amazon and no free shipping was given or offered by KVPet, only Amazon offers that deal but not on Nutrimalt, so although I love this product I am alas going to have to switch to something else from somewhere else who won't gouge me or my wallet.
