How do you use the internet for shopping?

Hi!

I use the internet for the majority of my shopping. Usually I will research what I am buying on the internet before I buy it and, then when I do but it, I will typically also buy it online because it is cheapest online. Is it easy in your country to buy things online? Do you find yourself using the internet to inform your purchasing decisions?

How would you buy an expensive electronic item like a television or phone? What about a cheaper item like a pair a shirt or toothpaste? If you do buy online what websites do you use?
