If you're looking to stock up on pet supplies, check out this deal on Amazon for Arm & Hammer pet waste bags. They have a 180-pack on sale for $7.56 (usually $17.99).
This is already a great price, but you'll get an even better deal when you check out with Subscribe & Save. Prime Day is in full swing, so now would be a good time to subscribe to five items or more at once and have them shipped to the same address. This will get you the maximum 10% Subscribe & Save discount, so you could pay as little as $6.80 for these bags.
