Given that Amazon controls about half of the U.S. online-retail market and takes in about 5 percent of the nation’s total retail spending, it’s encouraging to see pushback against the company’s hold on the market. But Dash buttons are hardly the problem. Amazon made online shopping feel safe and comfortable, at least mechanically, where once the risk of being scammed by bad actors felt huge. But now online shopping is muddy and suspicious in a different way—you never really know what you’re buying, or when it will arrive, or why it costs what it does, or even what options might be available to purchase. The problem isn’t the Dash button, but the way online shopping works in general, especially at the Everything Store.

“They sent the wrong tea lights,” my wife announced recently, after tearing open the cardboard box Amazon had just delivered. “It’s the wrong brand, and 50-count instead of 75.” This is not so unusual, actually. Amazon moves a huge volume of goods, and its warehouse workers are poorly treated humans, not just robots. Errors are bound to happen occasionally.

On top of that, Amazon is more than willing to fix its errors. In most cases, you can return an item for a refund or exchange with a few button presses on the website or in the app. And when Amazon messes up, as in the case of our tea lights, the company usually offers free return shipping, and even free UPS pickup, so you don’t even have to leave the house to rectify the error. These are some of the reasons Amazon consistently ranks high in customer-service satisfaction: The company appears to give people what they want, including correcting problems when they arise.

But a customer-service orientation masks how Amazon has changed consumer expectations and standards as they relate to retail purchases. At BuzzFeed News last year, Katie Notopoulos wrote about how terrible Amazon’s website is, prompted by its offering her a subscription deal for bassoon straps (a product Notopoulos reported needing to replace once every two decades or so), and a warranty for bottle brushes (which cost $6.99).

Notopoulos’s examples just scratch the surface of all the possible confusions that can arise when shopping on Amazon: Products are offered for “Prime” delivery, which is supposed to mean two-day shipping. But sometimes Prime means four days or longer. In other cases, one color of a given product—neoprene AirPods-case cozies, for example, which I recently purchased—might be available via Prime, but another might not.

Even determining what’s available to purchase, via a keyword search on Google or Amazon, produces confusion far broader and deeper than the price fluctuations obscured by a Dash button. I recently tried to search for a heat-pump-compatible thermostat on the site. I got a litany of results, all thermostats for sure, but it was difficult to figure out which ones really worked with a heat pump. Eventually I gave up and resolved to visit Home Depot, which I still haven’t done. Another time, I tried to look for a 5-by-8-inch picture-frame mat on Amazon. But every other possible combination of mat came up instead: 8-by-10, 5-by-7, 8-by-8, 5-by-5. A hedge-trimmer battery I purchased came with a charger, but I didn’t realize it from the product description, so I ordered a duplicate charger as well—that charger arrived first, for some reason, and I had opened the packaging so couldn’t return it.
