Grocery Store Product Placement

Today while grocery shopping at Safeway, I noticed the product placement of specific products next to others. For example, limes and lemons convieniently had a small display next to the beer aisle since they commonly can go with beers like Corona. Another product that was placed to aid in the convienince of the shopper's experience is the tortillas are located at the end of the aisle with the salsa and other spanish types of foods.
