That is exactly what I have found in two WalMart stores. This is because high traffic display is prime space requiring premium returns against other customers competitive for space. Might change to lower cost if the turnover warrants....ie, the product brings in good money for the store.
Shelf Placement Getting your product into a store is a massive achievement, but, it’s just the first step in a longer process. Not all shelves are created equal, and it is no secret that eye-level shelves and endcaps are among some of the best locations for being seen by shoppers. Since your product probably won’t start off with premium shelf space, negotiating with retailers is a must for brands looking to improve their placement.
