Devin, co-founder of an outdoor gear brand

We came across this book by chance, just browsing around. I shared it with my leadership team and we ended up reading it together — each on our own, but discussing chapters in our Friday meetings. Not because we're a SaaS company (we manufacture climbing gear) but because the principles applied so naturally to our online store that it felt like it was written for us.

We sell harnesses, ropes, carabiners — products that have compatibility requirements. A specific rope works with specific belay devices. A harness fits certain body shapes better. For years, our recommendations were a joke. "Customers who bought this harness also bought this chalk bag." True, but useless. The chalk bag isn't why they're on the site. They need a rope that matches their harness.

After reading the chapter on catalogue architecture, I assigned our ecommerce manager to rebuild our product attributes. We now track: intended use (sport, trad, gym, alpine), diameter, length, UIAA falls, dry treatment, and so on. It took a month. The result is that our recommendation widget now shows compatible ropes when someone buys a harness. Our average order value on those transactions is up maybe 10%. But more importantly, our return rate is down. People aren't buying the wrong rope.

We also used the chapter on pricing ladders to redesign our rope page. We used to sell ropes individually, one price per item. Now we offer three tiers: rope only, rope plus a belay device at a slight discount, and rope plus belay device plus a rope bag at a larger discount. The middle tier is selling like crazy. The top tier acts as a decoy and makes the middle look like a deal. I recognized the Williams-Sonoma bread machine story from business school, but I'd never thought to apply it to a climbing rope page.

The book is dense. We didn't read every chapter — the one on SaaS trials isn't relevant to us — but we read most of them, and each one sparked a concrete change. If you sell physical goods with any kind of complexity, don't skip this one.
