Depends on the courier you use. DHL will be fast with delivery but arrival of the customs bill is always an event.
Case in point, I order electronics worth 18k, tax is 11k. The funny part is this mysterious G.O.K fee that is 5000 bob, with no explanations.
Bringing in stuff through post is a bit better on the customs part as you can declare lower during inspection, as you are there. DHL do valuations on their own, you can't be there to under-declare or tetea for yourself.
Or better yet, import through Salihiya or C.W Sourcing
. As fast as DHL minus the KRA nonsense.
