Most of your sales floor is never seen by your customers. So it’s up to you to bring your merchandise to their attention. So in modern retailing, I have noticed is that shops now have many special areas. Not one but many! In the supermarkets as well as the regular area, you will find the same product at the ends of a shelf, the entrance and cash register area. So rather than have one big section dedicated to a product or line they have several. There is often is no correlation to these items in this area but people look at it.
Try this
Reduce some of the area of a department and move some of these items into a special area. Make it noticeable put a nice sign advertising this area
This will maximise the reach of these products so giving you more opportunities to market your products.
And of course, tell me how it goes.
