Target (TGT) is once again holding its annual Car Seat Trade-In event, allowing parents to receive a discount on a new car seat while reducing the impact of plastic on the environment.

From Monday through April 17, consumers can take their car seats to any Target store and place them in a drop-off box near Guest Services for contactless recycling. The retailer said all stores are participating in the program.

Customers who trade in their old car seat will receive a 20% off coupon they can use towards a new car seat, car seat base, travel system, stroller, or select baby home gear, which includes playards, high chairs, swings, rockers and bouncers.

The trade-in offer is good on two car seats, allowing customers to redeem the offer twice. The coupons, which may be used in-store and online, are good through May 1.

To participate in the trade-in event and receive the 20% off coupon, customers must be enrolled in the retailer’s Target Circle program. To enroll in Target Circle, shoppers can sign up online at Target.com or in-store.

Target said it will accept and recycle all types of car seats, including infant seats, convertible seats, car seat bases, harness or booster car seats, and car seats that are expired or damaged.

All car seats will be recycled by Target’s recycling partner Waste Management.

Target first introduced its Car Seat Trade-In event in April 2016. The program has recycled more than 1,1 million car seats and more than 17 million pounds of plastic.

Shares of Target were trading at $202.25 as of premarket hours, up $1.53 or 0.76%.
