The new Walgreens in my neighborhood has about 10 feet of shelf space devoted to on-ear and in-ear headphones. The 2XL's have the top shelf and definitely Walgreen's top promoted brand in this space. Lower shelf contained a few Sony's and in-Home.
Walgreens has 8000 + Store (just o be clear). My Walgreens has the same layout as you see. I wrote on this previous as they gutted their multibrand displays and focused on just a few with Skullcandy having the lead.
I've done site design/ site selection consulting for the likes of Shopko, Target, Walmart and once sat in on a big site selection meeting at Target headquarters, on Nicolette Mall, with about 20 to 30 people including their marketing staff. The site considered was to be a remodel of a JC Penny mall magnet store. I was their to give them input on the condition of the existing facility, building and grounds. I was fascinated to learn of all the analysis they go thru to optimize sales per square foot. And so when I see a store like Walgreens I can keenly appreciate their product selection and placement. They cannot afford to carry too great of a selection. They have to get product selection and product placement just right. That 10 lineal feet of shelf space is very valuable real estate. For Skullcandy to have the top shelf is an incredible accomplishment.
