Petsmart has a promotion for 40% off first Cat Litter AutoShip, it stacks with the 35% off first autoship for a combined 61% off. Shipping is free at $49.
It is *supposed* to be a max discount of $20 per offer (total max of $40), but many people are able to checkout without the max discount limit being applied.
To repeat the deal, log out of your Petsmart account (if logged in), choose your product, on the right is "autoship", add whatever quantity (ideally to get to $49+ for free shipping). You can sign up for new membership at the time of checkout if you don't already have an account.
