My grandfather loves chocolate so much but he has a diebites so i want to buy a sygar free chocolate for him so anyone tell me from where i can buy it. 
If you live in the UK, Thorntons do a very good range of sugar free chocolates. My grandma says that these are the best ones she has tasted, they don't have the bitter taste that some do:  http://www.thorntons.co.uk/thumbnail/Chocolate-Toffee-Fudge/No-Added-Sugar-Chocolate/No-Added-Sugar-Chocolate/pc/2198/c/2212/2212.uts
