I've only ever recieved fish with heatpacks, never plants but then again i only recieved plants in the fall/summer, if you think they will freeze then have your customers wait on the shipping, if thats possible, other wise i say send it without heat packs, it's indoors most the time and mail/ups/fedex trucks are infact heated.
Then I saw it. I saw a mom who would die for her son. A man who would kill for his wife. A boy, angry and alone. Laid out in front of him, the bad path. I saw it. And the path was a circle. Round and round. So I changed it.
