re: Shipping macroalgae?

[SeaHorse_Fanatic]

If I ship from Burnaby, BC to Medicine Hat, AB, would shipping it via Canada Post work well. Is it necessary to ship via Expedited or Overnight? Never shipped plants before so I don't know how fast it needs to get there to survive. If need be, I can ship Greyhound, but that's much farther away than the local post office.

TIA,

Anthony
