Here's how to subscribe to get this deal:
See all Blue Buffalo items in the BOGO sale, then subscribe to two like items in the sale. There's no limit to how many times you can buy pairs of items and get one free.
If you're going to stock up with this sale (and you absolutely should), buy the highest-ticket item first, two at a time, with Subscribe & Save.
Once you subscribe to five unique items, the additional 5% discount will retroactively apply to all of the items in your delivery.
