It's Earth Day, a day to celebrate environmental protection and also when retailers encourage practices like reusing and recycling resources.
While some stores like J.Crew aren't offering free things, they're donating a percentage of proceeds to causes related to Earth Day.
Here are some examples of the best Earth Day freebies and giveaways, including discounted jeans and free crafts classes. But be sure to call the stores beforehand to check supplies and read the fine print for restrictions.
American Eagle Outfitters: Since April 11, customers can bring their old jeans to any store in the U.S. and Canada and get a 20 percent discount on a new pair until April 30.
