The end-of-aisle displays (known as gondola displays, if you care) cost the food-and-drink companies quite a bit of money, because it is considered that people are more likely to notice (and therefore buy) things on them. So if you have a product to launch or relaunch, your marketing budget might cover advertising, coupons and gondola displays. It clearly doesn't work on you; thousands of marketing departments are probably rethinking their strategies as I write.
And yes, I did formerly work in FMCG.
