If your store caters to kids, make their shopping experience a delight, please their parents and have a chance to sell even more.
Offer a service to the parents where they order the kid’s present in advance. You gift wrap it for them and hide it somewhere in the store. You also write the kids name or otherwise mark their gift wrapped package with ink only visible in UV light. When they arrive, you give the child a magic wand (UV torch), and they go through the store searching for their hidden treasure.
