Maybe it's just the way I define "high value?" That's high-dollar-value (price) per cubic inch/cm of store display space. Let's say a two-pack or three-pack of AirTags priced at $49.99 in a box similar in size to a Lightning to USB cable or an iPhone leather case (very much the way Tiles are packaged). In terms of revenue-per-cubic-inch/cm, iPhone, Apple Watch, MacBooks, and the accessory wall are far more profitable than the average iMac or large screen display (the answer to the question, "Why doesn't Apple sell an actual Apple television?").
This is why a fairly small gourmet foods shop does so well on a sales-per-square-foot basis. $40 bottles of artisanal extra-virgin olive oil, wedges of $35/lb. cheese, tiny $10 envelopes of Spanish saffron, $25/lb. Parma ham, $10 loaves of bread vs. $2 bottles of ketchup, $5/lb. pre-sliced American cheese, large packages of common table salt, $5/lb. domestic ham, and $2.50 bags of hot dog buns at the supermarket. Sure, the supermarket is drawing a much larger clientele and selling a much wider variety of goods, but the scale of the enterprise has to be huge in order to be profitable.
