DAZ has an 800 number that always gets answered...call them up...suppose if you're out of the US, email or mail is the only way. They are very good at honoring their discounts. All you have to do is inquire, and they will handle it.

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
