Use rate calculator from
https://www.shopandship.com/en/home to calculate the cost. use the shipping weight. usually the shipping weight is bigger than the item weight.
amazon listings usually have correct shipping weight.
Aramex will clear custom duty for you. so it's not like receiving small items from ebay. duty will be added to your total cost.
for small items less than or around 1KG, this is the cheapest option.
