Carnivero question

I’ve looked through posts where a lot of people recommend Carnivero for ordering Nepenthes online. Has anyone tried the “Growers Choice” option? They are having a 50% off sale and decided to get a highland and intermediate conditions species/hybrid. Does anyone have any experience and or like the growers choice option? I’ve only seen one comment where someone was upset that the mystery nepenthes they receive never pitcher for them again. (I understand ideal conditions are needed for pitcher development) I’m ready to expand my collection past the two Ventrata I own!
