wsj.com: Will Christmas Trees Light Up Retail:
“The gap between Christmas-tree and store sales may be a sign that the shift in spending away from brick-and-mortar retailers and toward online shopping, and experiences over things, has intensified this year. Put simply, people would rather spend money at Amazon, or on meals and vacations, than on stuff at the store. That may explain why Christmas-tree sellers aren’t getting hurt by the changed environment.
For many people getting a tree, hauling it home and trimming it counts more as buying an experience more than it counts as buying a thing.”
