Alibaba or Ali express, shien... Non of them have an office in Ethiopia and if somebody told you that they're scamming you. If you want to buy from Alibaba and alike you need to get a mastercard, hulucard or whatever to pay in Dollars and once you do you can check the price of the products, their Shipping options.. and after that you will get your item through the post office or other carriers. Your products might be subjected to high tax so make sure to check beforehand or try it with smaller amounts. Good Luck
