by Carter Dougherty and Katrin Bennhold, International Herald Tribune, France - When the local bakery increased the price of a baguette for the third time in six months last year, Anne-Laure Renard and Guy Talpot invested in a bread-baking machine. When gasoline became their single biggest monthly expense in January, they decided to sell one of their two cars. Now, as everything from baby milk to chocolate desserts drives up their living costs, Renard, a teacher, and Talpot, a mailman, are planning their most radical lifestyle change yet: They are getting married to reduce their tax bill.
