I recently ordered a Nepenthes Robcantleyi and Nepenthes spathulata x dubia from Native Exotics and I got to say I am impressed!
First off I asked questions about the Nepenthes Robcantleyi and Ryan, the owner, answered my questions with quick responses. He was straight forward and was very welcoming. The delivery time was extremely fast too, I placed the order sunday night and only took 3 days to come in. When I received the plants, they were packaged with lots of care to protect the plant from harm during shipping. The only exception was that Nepenthes Robcantleyi had some of the potting mix spill(probably from the UPS guy), but wasn't a complete disaster.
Overall Ryan from Native exotics is a wonderful seller of Nepenthes. He is very welcoming and allows for questions with quick responses. Plants will come in with little to no harm! I was would my experience a 9.5/10.
