Meow Mix Seafood Variety Pack

Why is it so difficult to order this box of kitty food for my cat? 

My older cat loves these flavors and I have the hardest time finding this particular box, and when I do find it, they only have one box left in stock and you can't order it......you have to go to some distant city to pick it up.

I tried ordering 4 boxes this morning for delivery, but when I went to check out and complete my order they wouldn't delivery it.  Everything else on my list will arrive in a few days, but not this.  This one item could only be picked up in person from the Danville, Kentucky Walmart Store.  They would bring it out to my car, but it's not for delivery.

Why do they make you go inside a store for some things, and for other items you can drive up to the store and they will bring them out.  Then   there are even other items that you can't even order those things online either.  All this stuff is non perishable, so what's up with this stuff?  For some of us who have trouble walking, why not just let us order whatever we can pay for and deliver it to us?  And if its perishable, why can't you bring it out to the car for us with the rest of our order?  Makes no sense to me.
