Example 1 (custom hardware). My wife and I run https://littlebird.com.au and ship 25K orders per year. We found that it was taking too long to fulfil each order using Australia Post. So I built our own custom WebUSB postage scales and label printer. Creating a consignment is now 1-click. This enabled us to take the fulfillment process down from 5 minutes to 5 seconds. Across 25K parcels this equals 11-months of work…
Unless I'm completely mistaken, who knows.
