Waiting is normal (and a good thing) unless you order something when the temps are ideal, or nearly ideal, Both origin and destination.
If the orchid is exposed to cold, there could be a lot of damage. If you want to see what I mean, you can check out my thread "Suffering bellina" that is a couple weeks old at most. My second to last post or so has two photos of the damage that happened from being exposed to 20°F - 25°F, upon arrival.
**I'm not trying to bring up anything other than the damage that can occur from being exposed to the cold. The photos are good examples of what can happen.
Hopefully it all works out and the plant is healthy when you recieve it.
What kind of paph?
