Use This Sun-Activated Coupon for Android to Get Discounted Sunscreen

Here’s a clever product promotion masquerading as a coupon: Zealios, a skin-care company, is offering a digital 50 percent discount that gets activated when you spend some time out-of-doors. This is likely the most high-tech sunscreen coupon you’ll see advertised.

To use the sun-activated coupon, you will have to be on an Android phone and a Firefox browser. Once the digital coupon detects sunlight, you can use it to purchase sunscreen at 50 percent off of the company’s website, not at a brick-and-mortar store or even Amazon.
