Z1Motorsports offers NO REFUND if you send back a core (ie: upper intake manifold for porting service) that arrives damaged due to bad packaging.
Please consider doing something like that, everything properly detailed. Now with this bad experience you can discount a lot if it's oil in the packaging and zero refund if damaged. Saying that beforehand will ensure that the customers put a bit of effort to do thing right when sending it back to you.
When money penalty is involved things change.
