nbest buy: Unit head of Shoppers’ Stop, Elgin Road, Naveen Misra advises: “Listen to the announcements that are constantly aired. This helps you to check out the deal that you want. Look around for display signs that state the best deals so that later you don’t regret that you’ve missed out on some special offer.

nno exchange: No such condition can be forced upon the consumer. “If you spot any shop putting up such a signboard, get in touch with the legal metrology department of the ministry of consumer affairs, West Bengal government,” says Prabir Basu.

nsafe bill: While purchasing, ask for a cash memo. You can demand an exchange only if you can produce the bill. Your local shopkeeper may scribble something on a chit of paper and assure you that there won’t be a problem in exchanging the product later, but don’t buy that assurance.
