some updated info.
(1) 2 units to south africa: 2*150=300$, shipping cost=81$, paypal(3%)=11$, total cost= 462$
(2) 1 unit to greece: 1*150=150$, shipping cost=35$, paypal(3%)=5$, total cost=190$
(3) 15 unit to USA: 15*150=2250, shipping cost=161$, paypal(3%)=72$, total cost=2483$
so to SA might not be so good even direct it might seem that no matter how i ship to SA its just going to cost.
Please check with sam to find out the order price of 2 units shipped to sa from what my supplier tells me it going to be expensive. around 45$ a unit. so maybe a better deal to go with sam or it may not be.
