It costs somewhere from $25 to $50 per month ($300 to $600 per year) to feed a dog–the main variables being the size of your dog and the quality of your food. Cats cost about $30 per month for food and treats. . . add in litter you’re looking at over $360 there too. And if you’ve got multiples. . . well then this article is definitely for you.

In order to save on pet food, you first must always calculate unit cost, in this case cost per ounce or per pound. Unit cost is the only way to compare what you normally pay with prices at other retailers. That’s what I did when I went through every pet item at Costco and Sam’s and compared them all to Amazon.

These are Sam’s and Costco’s regular prices. Based on my research, it’s safe to say when either store runs instant savings, their prices are largely unbeatable.

 

Amazon or Costco: which membership is worth it for pet deals?

Costco’s memberships cost $60 per year (Gold Star) and can go as high as $120 per year (Gold Star Executive). Amazon Prime memberships cost $139 per year.

But do you need both? For pet parents, Costco is a great place for everyday low prices, but some products are actually cheaper on Amazon.

 

Amazon subscribe & save prices rival and sometimes even beat Costco’s.

Amazon’s automatic reordering program is called Subscribe & Save. If you’re not familiar, we wrote a post you can read on how Amazon subscriptions work.

The basics are:

  • You’ll save about 5% just for subscribing.
  • You’ll save 15% if you subscribe to 5 or more items per month. (When you browse our best subscribe & save deals, reaching five will be easy.)
  • You may be able save an extra 25% or more (in addition to 15%) when you subscribe to a new item. (I say ‘may’ because these extra discounts can vary from account to account. You may have nothing. You’ll likely see the 25%. Or you may even see a 40% in the place of 25.

In order to beat Costco, Amazon shoppers usually have to take advantage of all three.
