Aliexpress X Posta

I ordered some things zikafika posta. I always just ordered and had to deal with Speedaf. I am curious on why my products are taking so long. What is the process of dealing with posta. I have a friend who works there and told me bado haijafika alafu akasema zinafika huko kama kuna story ya ushuru 😂😂but siamini. Anyway who has ordered and had successful orders by Posta. Process ni gani wadau. Nafile ushuru wakiona ama namna gani.
