We saw this promo at Whole Foods Market in New York City. Pons Olive Oil stands out from all the competition by having a Bottle Necker on-pack promotion. They are offering a small pourer so that when the Olive oil is on the table it can be served in a more fashionable and drip free way.
Similar promotion would work well for Spirits companies. Similar promo for airing (decanting) wine might also work.
