Hi,
This is not a CX privilege. Here in Brazil we have the same problem.
You cant just browse a website and ask for something you need. If items are
heavy and expensive, its a budget nightmare to bring it in. High shipping
costs,
and high taxes (sometimes up to 100% the product value, depending on shipping
method).
So, the way is to wander around junkyards and collect everything that seems
like
would be useful for a QRO project. You end up with a love of junk in the attic
(wives love it) and there are always some parts missing...
73,
Felipe
