I’ve been getting IO auto shipped every month for over a year. The fifty gallon bags are usually cheaper than the box for some reason. Plus if I get a box it’s usually mangled and my delivery driver isn’t very happy with lugging heavier parcels. I had the salt, dog and cat food, as well as litter all autoshipped on the same day…..don’t do that. Your delivery driver will green light you! I broke them up into separate ships on different days while still hitting the free shipping on all. The delivery drivers appreciate the lighter loads. They often have sales, so be on the lookout. I’ve been getting all my supplies shipped to my door since I can’t drive anymore. As long as I don’t dump the kitty litter in the mixing station and the salt in the litter robot everything’s good!
