I broke the clip on a Plano tacklebox that must be at least ten years old. My fault.
[sales@jmgillies.com.au] (the Australian Importers) posted out a replacement clip.
When I emailed to ask the cost and postage, this was the response:
"There is no charge, Plano's warranty covers latches and handles etc for the life of the box."
I had to tell someone.
