Here is the calculation for a 2.5kg item I tried to buy from USA and ship back to Malaysia via a shipping company:
- Comgateway: (http://www.comgateway.com/rates-and-fees/ )
1st 0.5kg: 20.75
each additional 0.5kg: 3.25 x 4
Fuel Surcharge: 11%
speed: 5-8 days
Total: (20.75+3.25*4)*1.1 = USD37.125
Base charge: 20.40
Weight Charge/KG: 9.40
Fuel Surcharge/kg: 1.60
Total: 20.40 + (9.40+1.60)*2.5 = USD47.90
But with new account, first shipping discount 15%, so
Total = 47.90-15% = USD40.715
Rate is similar to Comgateway.
But with current USD/MYR rate of 4.42, have to think twice for any purchase made.
