Just multiply your pledge to get multiples of the reward.
International shipping is still a flat $10. Free shipping for USA.
For example, if you want 6 x Pearls (2 x Red, 2 x Silver, 2 x Gold)
Just multiply the 3 x Pearls pledge amount by 2 times.
So it's $138 ($69 x 2) for early bird USA shipping
or $168 ($79 x 2 + $10) for regular bird International shipping
