Found an interesting post on Infosys website:
It is possible to create a unique shopping experience for grocery shoppers in the brick & mortar world. I believe this will create a unique differentiation in the minds of shoppers who are looking for a better shopping experience in the grocery stores. This will create loyalty resulting in the Grocers ability to command higher prices leading to better profitability in the long run.
