Using Standard International Shipping (averages 10-16 days) and to avoid GST, the maximum should not go beyond 12 copies.
Based on FX rate of 1.65 (estimate). If order alone, it will cost SGD42.16. In bulk, we can save SGD9.00 - SGD10.40 each depends on quantity. We can arrange the collection during our monthly gathering if not in hurry.
Caution: FX rate based on estimation, actual rate may vary. Computation rounded up to 2 decimal place.
p.s. Can someone verify that my calculator is working properly..
