Target is unofficially tying in to September's designation of "Baby Safety Month" by running a car seat trade-in event, promising shoppers a coupon for 20% off a new car seat, stroller or other qualifying baby gear when they recycle their used car seat at the mass merchant from Sept. 3-13. Shoppers receive the coupon after bringing their used car seat to Target's "Guest Services" department in stores. An in-store standee, a feature in the retailer's Sept. 1 circular and a target.com promotional page touts the offer. 

The mass merchant runs a similar promotion tying in to Earth Month in the spring.
