As a store manager selling shoes in 1991 my boss told me that I needed to keep the displays fresh. "If this was your store and you wanted to excite people into buying, you'd be onto everything".
I remember Gary Parsons' advice well.
So it's cool how on a marketing level, Krispy Kreme has managed it well. It takes planning to have a product all planned and priced out with suitable promotional material. Just a little clever.
