I recently ordered some stuff from Nuts.com.
During checkout, they offered upgraded heat-resistant packaging to help prevent melting due to the hot weather. That was a great step. That alone is more than most would do.
However, then they went the extra mile.
Right before the final checkout step, they explained that the upgraded packaging is good for about two days, but since I ordered on a Friday, my shipment might sit at the UPS/Fedex warehouse over the weekend which would push it out beyond two days. Then they made it really easy for me to change my ship date to Monday to help prevent the melt.
That’s great defensive design. You rarely see it done so well – especially with the collision of all these special conditions (product type, weather factor, packaging type, weekend factor).
Great copywriting, too.
Very well done.
