In Hannaford, theres a three star nutrition guidance information provided for most items. The higher the star rating, the more nutritious the food. From 1 upto 3 stars, it indicates foods that are low in fat, high on whole grain, fibre etc., relatively. Its a pretty neat system and quite a good indicator of the stuff we usually buy and ideally should be buying.
Then there are self check outs where you can scan your own items and pay on your own without using a cashier at the end.
Reliance better take note of these emerging trends :)
