I've already come across this just this past Tuesday. We are currently in the season where new LEGO products get added to store shelves. Well, as you can see below, boxes for these newer sets were found near the toys department just laying around open for customers to browse. If one wasn't open, than customers should ask an employee for assistance. Having spotted a set among these boxes that I was interested in I did just that.
Let me be clear by saying these new products do have spots on shelves for them. Employees just hadn't gotten around to stocking them yet.
This still doesn't exactly help the situation by having even more product added to the top shelf. Some of these products on the shelf here can no longer be found elsewhere.
Hope this works out well for Kmart. Apparently Costco and Home Depot already use this same strategy, so it is not nothing new. This will also likely lead to less square footage being needed for each store.
