(CNN) -- Kohl's brought Amazon into a small number of stores almost two years ago. Now Kohl's is throwing its full weight behind the partnership.
The department store announced on Tuesday that it will accept Amazon customers' order returns for free, even without their shipping box at all of its more than 1,150 U.S. stores beginning in July.
Shoppers can drop off their returns at customer service desks, and Kohl's will package and ship the items back to Amazon using its own logistics network.
The plan marks a major expansion of Kohl's relationship with Amazon.
Kohl's began accepting free returns for Amazon customers in 2017.
The retailer started a pilot test with Amazon at 82 stores in Los Angeles and Chicago at the time and has since added close to two dozen stores in Milwaukee.
Kohl’s hopes the move will drive traffic to stores.
Separately, last month Kohl's said that it would sell a small selection of Amazon merchandise at more than 200 stores.
