What this
one catch saved.
10hrs
Dev time saved
Shipped, a complete checkout regression on a $3,000+ product is an all-hands moment, someone has to triage it as critical, reproduce it, identify what broke in the checkout routing, ship a fix, and verify it's resolved.
$3,148
Per lost sale
Every customer who clicked checkout during this window walked away empty-handed. On a product with an average order value of over $3,000, each lost conversion is a significant hit.
2hrs
Manual QA time
This one is actually quick to catch manually, anyone clicking through a basic purchase flow would hit it immediately. The real cost is how long it might have stayed live without automated testing.

Incorrect values
A single-step exploratory run on Eight Sleep's site. Spur navigated naturally through the purchase flow, closing modals, accepting cookies, browsing to the sale, selecting a product size and failed the moment it hit checkout. Seven actions in, before any payment details were ever needed.
