It's especially not how people shop at Amazon. You could feasibly imagine a shop where there is basically 1 version of each thing. Like the low cost supermarkets in the UK, they're efficient because they have very small product inventories. In that scenario you say "I'll buy some ketckup" and they only have 1 ketchup so you don't need to see it. You know the shop, you know what you're getting. Amazon is the polar opposite, for any given product it'll have 100,000 options and you have to fight Amazon every step of the way to find what you want, not just what will give Amazon the fattest margin.
