Waterlily,
I have found another site:
http://www.tiag.com/
If you click on Lavender and lace it brings up lots of kits.
And then if you click on the quiltmaker it shows all the threads
There is also a note about gold thread - and suggested alternatives.
Could it be the gold metallic thread that you need to get separately?
Added:
if you scroll to the bottom of the first (main) page, there is an email address for customer services
