The same could be said about just about any "work" that involves using a computer. It takes complete focus & attention, some effort, and knowing what you're doing. It's not exactly easy. What? Complete focus & attention? No. Effort? No. Not easy? No. If you have like 200 tabs open, you have to pay extremely close attention to make sure you catch the one that "makes" it in. I can't sit there and watch TV while I'm doing it. It's also a pain in the ass and there are plenty of people who wouldn't bother making that much of an effort or dedicating that much time to it. To do it, you HAVE to dedicate that block of time to it because you really can't do anything else. Once you actually do get in, it's a race against the clock to make the purchase and get it through before you lose that window, which is a pain in itself.
