I don't order cat food online. Mostly it's the cost... people say that online places are cheap or economical... HA! Besides shipping costs (sometimes free, IF you spend a lot of money), the food itself is about twice what I pay at the local grocery store.
9 Lives costs are before shipping and taxes:
Winco (local store) = $0.36/can
PetFoodDirect = $0.65/can
PetFlow = $0.61/can
Petco = $0.43/can (online "club" price)
Petsmart = ? (they don't seem to have it) - I used to get Authority, but even that "generic" stuff has gone up to $0.74!
And yes, I realize 9 Lives probably isn't the best stuff. But it's what I can afford, and kitties only get 2.5 oz of it a day anyway (half a can each), just for a little treat - and slightly more moisture for Paizly's UTI issues.
I do try to get the flavors with the best ingredients first...meat/meat-stuff in at least the first 5.
I go to Winco every couple weeks for my own groceries anyway, so it's not an "out of the way" thing. Convenient, cheap, and basically hassle free!
