The secret of successful retailing is to give your customers what they want.
And really, if you think about it from your point of view as a customer, you want everything:
- a wide assortment of good-quality merchandise;
- the lowest possible prices;
- guaranteed satisfaction with what you buy;
- friendly, knowledgeable service;
- convenient hours; free parking;
- a pleasant shopping experience.

This is absolutely true. Sam Walton set standards which other guys like Target, Best buy and Home Depot have successfully emulated.
I am as excited by the Bharti Walmart tie-up as you are. The question is whether we can see these principles being applied in India too.
