Online shopping

I keep hearing this buzz about how great and how easy online shopping is. Yet everytime I take the hour worth of time to actually browse around at what I want, and type in all my information there always seems to be a error. Never can it just work, always something wrong. I feel like I just wasted over an hour of my time looking at things and wanting them. To just get off the computer irritated and having nothing new show up on my door step! I love how technology is slowly evolving into everyday activities but at least work! It is extremely irritating, and I guess something I will have to learn more about.
