Shelf trays accompanied by shelf blockers stocked the new Dove VitaminCare+ aluminum-free deodorant while the attached blades spotlighted Schmidt’s natural deodorant. The power wing stocked Secret and Old Spice dry sprays under a “build your beauty ritual” header.A promotional page within Meijer.com dangled $5 off the purchase of $15 worth of Unilever products.

The displays encouraged shoppers to “experience full-court freshness” with Axe, Dove Men + Care and Vaseline Men.Unilever used that same message to run a sweepstakes with Walmart awarding tickets to the Final Four. Consumers could enter from March 1-20 by sharing a video of them making a full-court shot on Instagram and tagging Walmart, Degree, Dove Men + Care and Axe.
