If you want more customers act on getting them to do business with you. Complaining or wishing will not get them trading with you. Only your action through advertising, marketing or knocking on their doors will work for you.
I know of newsagents growing stationery and ink sales through knocking on doors. I know of newsagents growing toy sales through knocking on doors.
Yes it’s hard work and you probably did not buy your newsagency to be a door to door sales person but if you want to grow your sales this is one marketing activity you ought to embrace.
Every day you are not knocking on doors is another day a competitors could be doing it and grabbing sales that could have been yours.
Being in retail does not mean all your business has to be done in the shop!
