Pet Food Express vs. Petco vs. PetSmart: Which Has Better Food & Wash Prices?

Choosing where to buy pet food used to be simple: find the closest store, grab the usual bag, and head home.

Today, it is a little more complicated.

Pet owners compare prices across apps, loyalty programs, online subscriptions, in-store sales, grooming services, and self-service wash stations. A store with a lower price on one bag of food may be more expensive once delivery fees, membership conditions, or wash costs are included. Another store may charge slightly more for food but save time by offering a dog wash, grooming, pickup, and supplies in one trip.

That is why Pet Food Express, Petco, and PetSmart are worth comparing carefully.

All three are popular pet retailers, but they serve slightly different shoppers. Pet Food Express tends to appeal to owners looking for specialty food, natural products, and self-service pet washes. Petco offers a broad ecosystem of food, supplies, grooming, and other pet services. PetSmart is known for its national presence, major brands, frequent promotions, and large selection of products and services.

So which one offers the best value?

The answer depends on what “value” means for you. If you regularly wash your dog yourself, Pet Food Express may come out ahead. If you want the largest food selection and online convenience, Petco or PetSmart may be stronger options. The smartest way to decide is to compare the total cost of caring for your pet—not just the price tag on a bag of kibble.

A Quick Comparison

Pet Food Express offers self-service pet wash tokens for $20, with an Exclusive Rewards benefit that gives eligible shoppers a fourth wash free after buying three. That brings the effective wash cost down to $15 when the offer is used consistently. Petco’s self-service dog wash starts at $20 at participating locations, although availability and final options can vary by store.

Pet Food Express: Best for Frequent Washes and Specialty Food

Pet Food Express has a different feel from a big-box pet retailer.

Rather than trying to be everything to every pet owner, it often focuses heavily on food quality, pet nutrition, specialty products, and practical services like self-service dog washing. That makes it especially appealing to people who spend time researching ingredients, switching diets, or buying frozen, raw, limited-ingredient, and premium food formulas.

For dog owners who use a wash station regularly, Pet Food Express has one of the clearest value propositions in this comparison.

A single self-service wash token costs $20. The wash area typically includes the equipment that makes washing at home inconvenient: an elevated tub, shampoo, conditioner, towels, dryers, and a cleanup area. The exact setup may differ by store, but the point is consistent: you avoid a clogged bathroom drain, wet towels throughout the house, and a dog trying to escape the tub.

The loyalty advantage matters if your dog needs frequent baths. With the buy-three-get-one-free reward, four washes cost $60 rather than $80. That works out to $15 per wash.

For a dog that loves mud, visits the beach, sheds heavily, or gets dirty during regular outdoor walks, that recurring saving can add up quickly.

Where Pet Food Express stands out

• It is especially useful for owners who buy premium or specialty diets.

• It has a focused shopping experience for pet food and wellness products.

• Its self-service wash reward can lower the long-term cost of routine bathing.

• It may feel less overwhelming than a giant store with dozens of unrelated product categories.

Where it may not be the cheapest

The challenge is that specialty food often has a higher price point than conventional grocery-store or mass-market brands. That does not make it overpriced; it simply means shoppers need to compare the same product across retailers.

A premium 25-pound bag may cost more at Pet Food Express than a basic formula at a big-box retailer, but those are not equal comparisons. The useful question is: What does your pet’s exact food cost per pound at each store?

Also, Pet Food Express has a smaller physical footprint than Petco or PetSmart. If the closest location is far away, the benefit of a loyalty wash discount may disappear after factoring in fuel, time, and convenience.

Best fit: Pet owners who value specialized food choices and plan to use self-service washing often.

Petco: Best for Convenience and Broad Choice

Petco is often the strongest option for owners who want one retailer to cover several needs at once.

Food, treats, toys, flea prevention, cat litter, grooming, supplies, pickup, delivery, and other pet-related services can be handled through a single shopping ecosystem. That convenience matters more than people think. If you are already visiting for food, adding a nail trim, a new leash, or a self-service wash can reduce the need for separate errands.

Petco’s self-service dog wash starts at $20 at participating stores. Like Pet Food Express, the service is designed to make DIY bathing easier by providing the tub, supplies, and cleanup setup. For someone who only needs an occasional wash, the starting price puts Petco in direct competition with Pet Food Express.

The main difference is that Petco’s wash value is often based on convenience rather than a clearly advertised repeat-wash reward. If a Petco with a wash station is closer to your home, it may be the better real-world choice even if another store saves a few dollars over several visits.

Petco’s food advantage

Petco usually offers one of the broadest product selections in the category. That matters because pet owners do not all shop the same way.

Some buy dry food in large bags. Others need wet food, frozen food, raw food, prescription diets, kitten formulas, senior formulas, sensitive-stomach recipes, or breed-specific products. A large assortment creates more room to compare ingredients, package sizes, and prices.

Petco can also appeal to shoppers who prefer online ordering, same-day delivery options, store pickup, and recurring deliveries. Those services can make a noticeable difference when you buy bulky items such as litter, large food bags, or cases of canned food.

What to watch for at Petco

The biggest mistake is assuming a promotion automatically makes a product the best deal.

Before buying, compare:

• The standard price.

• The temporary sale price.

• The price per pound or ounce.

• Whether a discount requires a recurring subscription.

• Whether shipping, delivery, or minimum-order rules change the final cost.

• Whether the same formula is cheaper in a larger size.

A “save 20%” offer may look attractive, but it may still cost more than another retailer’s everyday price. On the other hand, a regular delivery discount can be excellent value if you purchase the same food consistently and can manage the timing.

Best fit: Pet owners who want wide selection, digital convenience, and multiple pet-care services under one roof.

PetSmart: Best for Major Brands and Promotional Shopping

PetSmart competes most directly with Petco in terms of scale and shopping style.

Like Petco, it offers a broad range of food brands, toys, habitats, supplies, grooming services, and pet-care products. For many households, it is simply the most accessible option because of its national presence and large-format stores.

PetSmart can be a strong choice for owners who buy well-known national brands and are willing to compare promotions before checking out. Its size and frequent sales activity make it useful for price-conscious shoppers who do not mind taking a few minutes to look at weekly offers, app pricing, pickup options, or bundled deals.

The food-price advantage at PetSmart

PetSmart’s strongest food advantage is choice.

When stores carry multiple package sizes and several competing brands, shoppers can compare products directly. This is particularly helpful for households with more than one pet, because larger bags, multipacks, and recurring purchases can lower the cost per serving.

But bigger is not always better.

Buying the largest bag only saves money if your pet will actually eat it before it goes stale. Dry food can lose freshness after opening, and some pets become bored with a formula or develop dietary needs that require a switch. The lowest unit price is useful, but only when it fits your pet’s routine.

What about dog washes?

PetSmart’s grooming services are widely recognized, but self-service wash availability is less standardized from location to location than the published Petco self-wash option. That means PetSmart may be worth considering for professional baths or grooming packages, but it is harder to treat as a reliable, nationwide DIY wash-price comparison.

Before making a special trip, check the local store’s grooming and wash options. A nearby PetSmart may have an excellent service package, while another location may not offer the same option at all.

Best fit: Owners who buy popular food brands, monitor promotions, and want grooming or supplies alongside food shopping.

The Real Food-Price Test: Compare Unit Cost

The most reliable way to compare pet-food prices is not to ask which store is “cheapest.”

It is to compare the same product in the same size—or calculate the unit price when sizes differ.

For example, imagine your dog’s food comes in two bags:

• A 12-pound bag for $36.

• A 24-pound bag for $60.

The first bag costs $3 per pound.

The second bag costs $2.50 per pound.

The larger bag is cheaper per pound, saving 50 cents for every pound of food. But that does not automatically make it the best purchase. If your dog only eats a small amount each day, the food may sit open too long. If storage is difficult, or if your pet has a sensitive stomach and may need a food change, the smaller bag could still be the better practical choice.

Use this simple calculation:

Unit price=Total priceWeight or quantityUnit price=Weight or quantityTotal price​

Compare the final unit cost after loyalty rewards, coupons, subscriptions, and pickup discounts are applied.

This is particularly important with canned food. One can may look inexpensive, but the actual feeding cost may be higher than dry food because your pet needs multiple cans per day. The best value depends on serving size, not just the price of a single item.

What “Better Value” Really Means

The cheapest store is not always the best store.

A better definition of value includes five things:

1. Food quality and fit
   The food must suit your pet’s age, health needs, preferences, and veterinarian’s guidance. A bargain is not a bargain if your dog will not eat it or cannot tolerate it.

2. True final price
   Consider sales, loyalty points, subscriptions, delivery charges, and purchase minimums.

3. Time and travel
   A store that is 25 minutes away may not save money once fuel and time are included.

4. Service availability
   A $20 dog wash only helps if the location near you actually has a working self-wash station.

5. Shopping consistency
   If you repeatedly buy the same food and wash your dog regularly, rewards programs can matter more than one-time discounts.

So, Which Store Should You Choose?

Choose Pet Food Express if you buy specialty food, prefer a more food-focused store experience, and regularly use a self-service dog wash. Its $20 wash price becomes an effective $15 per visit when the buy-three-get-one-free rewards benefit is used.

Choose Petco if you want the best balance of food variety, online ordering, store pickup, and pet-care services. Its self-service dog wash begins at $20 at participating locations, making it a competitive option for occasional DIY baths.

Choose PetSmart if you shop major brands, enjoy comparing promotions, and want food, supplies, and grooming-related options in one large store. It can offer excellent value, but wash services and local pricing require more location-by-location checking.

The best long-term approach is not loyalty to one logo. Keep a shortlist of your pet’s regular products, compare their price per pound or ounce across stores, and use the retailer that offers the best combination of cost, convenience, and reliable availability.

Your pet does not care which store you choose. But your budget, schedule, and cleanup routine probably do.

Which matters more in your regular pet-shopping routine: the lowest food price, the easiest dog-wash option, or being able to get everything in one trip?
