AliExpress has started delivering its parcel via CPEX in Lahore city, a private courier company.
Now they will get your parcels cleared from customs and deliver it to you unlike Pakistan Post who were totally involved in thievery of international parcels.
Make sure you choose "AliExpress Standard Shipping" while placing order.
Still do not order 4G/WiFi devices/signal boosters and similar other electronics as customs will demand NOC from PTA.
