How does the sample return process work and how long does it take?
How much does it cost to return the sample to the lab?
Isn't the sample already broken by the time it gets to you?
Is it necessary to refrigerate the sample during return shipment and how long does the sample remain stable?
Do I have to sent back the sample on a certain weekday?
I no longer have the return envelope, what should I do?
What can I say at the post office when I want to post my sample at the counter?
