The moderators along with Phill discussed the Triffid order at the time. Phill decided it was fine as this is not a frequent occurance and people would most likely be ordering things not commonly available here in the US and it was a general good thing for folks to remain excited about the hobby! If it becomes a common occurance though, there may be reconsideration.
I would keep in mind though that there are US nurseries that do go through the trouble and expense of bringing in a variety of plants from various places overseas. So it is not just an issue with Nepenthes vs VFT etc and PFT. Just a general good policy to support domestic business.. even though it is nice to get the plant directly from the source for less than a domestic supplier. Plus a reputable domestic supplier will have acclimated the plant and in cases of Southern plants readjusted their dormancy cycle, if they have one. So while it may seem like a bargain it isn't always that much of a savings.
