I have a friend who is expecting to get 10lbs mailed to him and imo I would think that the Usps would catch on to that much at once. If it's a one time thing would you think that he is able to succeed in this? Does anyone have any stories related to this? For a further backstory, it's a grower in Cali that he knows very well (Lifelong friend) No DNM's being used.
Break it up into smaller shipments, jeez.
