I did a double-take in the pet food aisle when I saw boxes of candy for the pooches — but on closer inspection realized it was an illusion. Some clever marketer put a small number of treats in a re-branded box to increase the attention the treats garner (as well as the profit margin!).
Of course, the treats are aimed at the owner rather than the pet itself in an attempt to stimulate nostalgic feelings and set the kibble apart from the aisle of others — but I suspect the contents have not been changed.
As I have written before, it pays to take a fresh look at your offerings. The same thing in a different package can stimulate new interest, earnings, and impact.
