I have written here many times about the need for a USP, a Unique Selling Proposition, for your newsagency business.
It is equally important you talk about this uniqueness, that it defines the narrative of your business.
Face to face, on social media and elsewhere, talk about your uniqueness, use this as a platform through which to market your business. Use this to show all you are in contact with why shopping with you is better and more appropriate than them shopping with a competitor.
I appreciate this concept will be challenging for some. Take your time, work out your story. Test it. Once you have it down, go for it and expect to attract new people looking at your business to engage with what is unique about your business.
