I'm looking for an app that will notify me when a specific shipping option is selected. i.e. Our go-to shipping option is USPS priority mail, but we have a "Rush Order" option built into a shipping option, and I want to be notified when that option is selected. Otherwise a customer who paid for a rush order ends up in bunched into our consistent 4-week lead time.
Any leads on this would be really appreciated, thanks!
