Probably because there is a demand for their chocolates...I know I m hooked on their white chocolate truffles!...Its just another way to purchase goods without having to travel to the stores for the consumer and another way for Thorntons to gain extra custom by using the ever popular internet shopping phenomenon!
Maybe your question has the answerYou used Yahoo Answers (the internet) to try get an answer to your question.Why? Because you know lots of people use Yahoo Answers (the internet)So maybe Thorntons have a website cos they know lots of people use the internet, and so they know having a website will mean lots of people will get to hear about Thorntons, which they hope will mean more sales of Thorntons chocolates for them (which is what they re all about - selling chocolates!)
