Usually I like to shop around and compare prices, especially when it comes to food, but there are exceptions. For example, for Christmas I bought myself Bose 20i Acoustic noise cancelling ear buds and I absolutely love them. They were really expensive, but to me it was worth it. For electronics and the like I tend to go for the more expensive option because (in my experience anyway) it tends to last longer and I end up saving a bit more money in the long run, but even then, I will go around the stores and shop online to try and compare prices. I am actually really quite cautious with money.
