US retailers are increasingly offering returnless policies for unwanted products whose returns costs exceed their worth, according to a survey by goTRG.

The survey surveyed 500 executives at 21 large retailers, including Walmart and Amazon.com.

The study found that 59% of these companies offer such policies, reducing profitability by requiring transportation, sorting, and resolding at a discount or disposed of at a loss.

The study comes as Optoro expects US customers to return $173 billion in holiday purchases, 28% more than last year.

The study also highlights the importance of offering store credit, charging for some returns, and encouraging online buyers to return to stores.
