Purchasing sequins

I have been scouring the Internet for days for a source for a small
quantity of iridescent flat (or cup) 6mm sequins,

I live in New Zealand and can only find pearl lustre sequins here - no
clear iridescent ones. And they are expensive here!

One supplier in the USA only supplies internationally with orders over
$25 plus postage - and International postage is SO expensive!

Does anyone out there have another source I could try please? I would
be very happy to make some sort of private arrangement if necessary.

Also, I have (for the next week or so) a friend in the USA who would
receive the goods for me and bring them back next month. I would
need to communicate with someone on this newsgroup privately and with
complete trust. I am not sure if this is usual.

Thanks for any advice/caution/etc?

Cheers
Daisy
