A practical guide for retailers who want durability, shopper comfort, and lower long-term maintenance costs.

Choosing a new shopping cart program is one of those decisions that seems simple until you are living with it every day. A cart impacts how shoppers move through your store, how often your team is fixing wheels, how quickly carts nest on the front end, and how much you spend over the life of the fleet.

Below are five shopping carts that make a lot of sense in 2026, based on what retailers typically care about most: total cost of ownership, maneuverability, nesting efficiency, corrosion resistance, and serviceability. These are not the only good carts on the market, but they are five options that cover the most common store needs.

Disclosure: Carts and Parts, Inc. sells and services several of the carts in this guide, including Unarco models we represent, and we also supply an all-polymer cart manufactured by R.W. Rogers Company. The picks below are based on store fit and long-term practicality, not just brand.

What matters most when buying a shopping cart in 2026

Before the list, here are the criteria we see making the biggest difference for retailers:

• Total cost of ownership: A lower purchase price can disappear fast if wheels, bearings, and frames require constant attention.
• Maneuverability: Casters, tracking, and how the cart “feels” in tight aisles matter more than most people think.
• Nesting and front-end efficiency: Better nesting saves space and reduces cart corral clutter.
• Corrosion environment: Humidity, salted winter sidewalks, coastal air, and frequent washdowns can shorten the life of traditional metal carts.
• Parts and service availability: Even the best cart needs maintenance. The best program is the one you can keep running.

If you want your cart program to last, pick the cart that fits your environment and shopper behavior, then support it with the right parts and service plan.

1) Best overall for weekly grocery trips: Unarco M90ZX

If you are looking for a classic, high-capacity workhorse for a full-size grocery environment, the Unarco M90ZX is a strong candidate. It is built for the “big weekly trip” shopper, with the size and stability most customers expect from a primary fleet cart.

Best for: Full-size grocery, high basket loads, family shopping
Why it makes the list:

• Large, familiar format that works across most store layouts
• Built for day-to-day durability in a high-traffic environment
• A good anchor cart when you want one primary model across many locations

Tradeoff to consider: Larger carts can feel bulky in narrower aisles or small-format stores.

2) Best mid-size option for smaller footprints: Unarco M95Z

Not every store needs a large cart as the default. If your shoppers tend to buy fewer items, or your footprint is tighter, a mid-size cart can improve flow and reduce “parking lot traffic” inside the store. The Unarco M95Z is a practical choice when you want something versatile without going too small.

Best for: Mid-size grocery, neighborhood markets, stores with narrower aisles
Why it makes the list:

• A balanced size that still feels like a real cart for shoppers
• Often easier to maneuver and nest than larger formats
• Helps reduce congestion in tighter layouts

Tradeoff to consider: If your store serves a lot of large-basket shoppers, you may still want a larger model as your primary cart.

3) Best for quick trips and express shopping: Unarco M48 Max (two-tier)

Two-tier carts continue to earn their place in a lot of stores because they support a very specific behavior: quick trips, smaller baskets, and shoppers who want to stay nimble. The Unarco M48 Max is a good example of a two-tier cart that encourages “grab and go” shopping while still carrying more than people expect.

Best for: Express trips, pharmacies, small-format, urban stores, front-end convenience
Why it makes the list:

• Supports quick shopping patterns and faster movement through aisles
• Two levels help shoppers separate items and manage smaller loads
• Typically nests well, and can reduce cart storage headaches

Tradeoff to consider: Two-tier carts are not the best fit for large weekly grocery trips, and some shoppers prefer a traditional basket.

4) Best hybrid option with a plastic basket: Unarco PC-42

Some retailers like the idea of a cart that blends the feel of a traditional cart with the benefits of a plastic basket surface. The Unarco PC-42 fits that “hybrid” preference and works well in stores where appearance, ease of cleaning, and shopper comfort are high priorities.

Best for: Retailers who want a different look and feel than traditional wire carts
Why it makes the list:

• Plastic basket surface can be easier to wipe down and keep looking clean
• A good “middle ground” between classic wire and all-polymer carts
• A modern look that some stores prefer for brand presentation

Tradeoff to consider: Always confirm parts availability, service approach, and long-term maintenance expectations for any hybrid design.

5) Best rust-free option for harsh environments: Sustainable Plastic Cart (R.W. Rogers all-polymer)

If corrosion is a constant fight, all-polymer carts are worth serious consideration. The Sustainable Plastic Cart we carry is manufactured by R.W. Rogers Company, and it is built for retailers who want a cart that is rust-free and designed with replaceable components in mind. It is also a great option for stores that want a quieter cart and a different shopper experience than wire.

Best for: Coastal regions, wet/humid environments, frequent washdowns, stores wanting rust-free fleets
Why it makes the list:

• Polymer construction eliminates rust and reduces corrosion-related downtime
• Designed with replaceable parts, which can help extend service life
• Often a strong fit for retailers focused on long-term durability and appearance

Tradeoff to consider: All-polymer carts can cost more upfront, so the decision should be made with a long-term ownership view.

A simple way to choose the right cart from this list

If you are trying to narrow it down quickly, here is a straightforward way to think about it:

• Most stores want one primary fleet cart: Start with M90ZX or M95Z depending on store size and shopper behavior.
• Want to reduce congestion and support quick trips: Add M48 Max as a secondary cart.
• Want a modern look and a plastic basket surface: Consider PC-42.
• Rust is a real issue or washdowns are frequent: The Sustainable Plastic Cart deserves a close look.

A lot of strong cart programs are not one cart, they are a mix. Many retailers run a primary cart plus an express cart, and sometimes a third option for specific store formats.

Final thought: the best cart is the one you can keep running

No cart is maintenance-free. Wheels wear out, casters take abuse, and cart loss is real. The cart that performs best over time is usually the one that matches your environment and shopper needs, and has a realistic plan behind it for parts, service, and fleet upkeep.

If you want help matching a cart model to your store layout and shopping patterns, it can be worth doing a quick cart program review before you place a large order. A little planning up front often saves a lot of frustration later.
