Thank you for your reply. Most of the suppliers are trading company for piggy bank. i will search for manufacturer. i talk with one supplier they said price for 240 pieces $0.58 per piece and shipping cost is $175. i said shipping cost is very high. they said piggy bank size is large so this is reasonable shipping cost for that.
i calculate this price + shipping + custom charges the product price is more than Rs.100 for single piece. then how can i put margin. it is very confusing.
(they said small size product is less shipping cost).
