The hidden cost of ‘free returns’ for Amazon US

E-commerce may make shopping more convenient, but it has a dark side that most consumers never see.

Say you order an electric toothbrush for Father’s Day and two shirts for yourself from Amazon. You unpack your order and discover that the electric toothbrush won’t charge and only one shirt fits you. So, you decide to return the unwanted shirt and the electric toothbrush.

Returns like this might seem simple, and often they’re free for the consumer. But managing those returns can get costly for retailers in the US, so much so that many returned items are simply thrown out.

In 2022, returns cost US retailers about US$816 billion in lost sales. That’s nearly as much as the US spent on public schools and almost twice the cost of returns in 2020. The return process, with transportation and packaging, also generated about 24 million metric tons of planet-warming carbon dioxide emissions in 2022.

Together, costs and emissions create a sustainability problem for retailers and the planet.

As a supply chain management researcher, I follow developments in retail logistics. Let’s take a closer look inside the black box of product returns.

Returns start with miles of transportation

So, you repackaged your unwanted shirt and the electric toothbrush and drove them to UPS, which has an agreement with Amazon for free returns. Now what?

UPS transports those items to the retailer’s warehouses dedicated to processing returns. This step of the process costs the retailer money – 66% of the cost of a $50 item by one estimate – and emits carbon dioxide as trucks and planes carry items hundreds of miles. The plastic, paper or cardboard from the return package becomes waste.

Processing a return takes two to three times longer than initially shipping the item – it has to be unpacked, inspected, repacked and rerouted. That adds more to the cost to the company, especially in a tight labor market. Workers have to manually unpack the items, inspect them and, based on the return reason, decide what will happen next.

Restocking and reselling means more miles

If a warehouse worker decides the shirt in our example can be resold, the shirt will be repackaged and sent to another warehouse.

Once another consumer orders the shirt, it will be ready to be packed and shipped.

In-store returns can significantly cut warehouse and transportation costs, but driving to a brick-and-mortar store might not be convenient for the consumer. Only about a quarter of online purchases are returned in person to the store.

Refurbishing, if repair costs less than the product

If the item is defective, like the electric toothbrush in our example, the warehouse worker might send it back to the manufacturer for fixing and refurbishing. It would be repackaged and loaded on a truck and possibly a plane to be sent to the manufacturer, leading to more carbon dioxide emissions.

If the electric toothbrush can be repaired, the refurbished product is ready to be sold into the consumer market again – often at a lower price.

Refurbishing returned products helps to achieve a closed-loop supply chain where products are reused rather than disposed of as waste, making the process more sustainable than buying a new item.

Sometimes, however, repairs cost more than the product can be resold for. When it is more expensive to restock or refurbish a product, it may be cheaper for the retailer to throw the item away.

Landfills are a common end for returns

If the company can’t resell the shirt or refurbish the electric toothbrush economically, the outlook for these items is grim. Some are sold in bulk to discount stores. Often, returned products simply end up in landfills, sometimes overseas.

In 2019, about 5 billion pounds of waste from returns were sent to landfills, according to an estimate by the return technology platform Optoro. By 2022, the estimated waste had nearly doubled to about 9.5 billion pounds.

Era of free returns might not last

In the past, customers who wanted to return items by mail were often expected to do so on their own dime. That changed after Amazon began offering free returns and providing easy-to-use drop-off locations at UPS or Kohl’s stores. Other US retailers followed suit to compete, with many seeing free returns as a way to keep shoppers coming back.

But that pendulum may be starting to swing back. The percentage of US retailers charging to ship returns increased from 33% to 41% in 2022.

US-based retailers are trying several other techniques to lower the return rate, waste and losses, which ultimately come back to consumers in the form of higher prices.

Some retailers have shortened the return window, limited frequented returns or stopped offering free returns. Other strategies include virtual dressing rooms and clearer fitting guides, which can help reduce clothing returns, as can high-quality photos and videos that reflect size and color accurately. If consumers use those tools and pay attention to sizing, they can help cut down on retail’s growing climate footprint.
