Set up a Lubriderm sampling station in the aisle and ask the shopper if they need to take a 'Lotion break'? Then dispense a small sample from a machine similar to a hand sanitizer dispenser (does Lubriderm offer an anti-bacterial lotion? Not a bad idea!). Alternatively, dispense 'wipes' that are coated in Lubriderm. Once the shopper has come close enough, tell them to snap a picture of a QR code for $1.00 off of a family-size bottle of dermatologist recommended Lubriderm.
