I think so many terrible trends are driven purely by most people's over reliance on mobile phones. When you're at a personal computer, it's not terribly hard to search for the same product on multiple web stores and see which one makes the most sense, or build up a cart over a few days to hit a shipping minimum. For many things it's nice to know you're getting consistent quality rather than whatever fly-by-night gensym "brand" happened to rank in Amazon search. "Fast" shipping is overstated for Amazon and overrated for most purchases (on average, with the Sunk Cost Fallacy membership, I'd say it's a day or two quicker than other web stores). If you really do need something urgently then it's worth it to spend a little effort comparing who can actually get it to you the quickest. And over time you build up a regular intuition of where to shop for various types of things. Weighing the options is only hard when you've disempowered yourself by using a tiny touch screen with a hostile operating system.
