SVB is usually efficient and reliable......
Aliexpress will delay post by "upgrading"
your order to a combined delivery, if you have other orders in the system; so wait till tracking of your item indicates left the mainland between placing any other orders.
SVB's quick to get it away, but their packaging can be woefully almost non-existent (bubblewrap must be at a premium). I fail to understand why, if their mainstream business is optically driven.
