You can add this to cart and checkout with zero shipping fee and get a free SPOTMYUV sample pack. These are stickers that alert you when it's time to reapply sunscreen. Each SPOT lasts one day, up to 12 hours in outdoor sun. That's way longer than one GOOB, which only lasts about 3 hours in the sun before he zonks out.
