have a free shipping code around somewhere if you need it.
I've been using them for my cats food for a little while now and so far out of the delivery companies they have the best prices and customer service. If you set up the shipping it will just arrive on the dates you pick. I never have to think about when to order or anything
I'm switching the cats to raw slowly, but I'll probably be using them for a while yet. I have one hold out cat that refuses to touch raw
