(BBC) - New laws have come into force banning "irresponsible" drinks promotions by retailers in Scotland. Shops and supermarkets can no longer make offers such as buy-one-get-one-free and multi-buy discounts on wine. The Alcohol Bill also restricts alcohol advertising around premises, and brings in age verification requirements and a new tax on some licence holders. Tesco has told customers they will still get wine offers online because it will dispatch orders from England.
