LOL, I am actually of the opinion that the Nano is UNDERPICED, not the O-rings overpriced. I think your petition (if it gets of the ground) will be like, perhaps not the outcome you desire. Etc.
Also, like anyplace can charge what they want, for anything. I don't like that site personally and everyone I know who uses it gets shafted for the most part.
Perhaps you are an ali-er express genius or whatever, but if the O rings are genuine and your engines are not, I wouldn't suggest purchasing them (the O rings) they might not fit.
Petitions R us, this society. Vote with your feet and spend your outrage finding something that will work for less, however you do it you've gotten PLENTY of suggestions.
If you go "principle of the thing!" I am going to go
because we have SO much more excellent vaping principles to worry about than some 6 dollar O rings.
You do not have to buy them. You don't have to use your Engine. You can stomp on it with your feet in disgust, while WAILING out Job-like to your creator and it would be more effective than your desire to PETITION and BAN said company. Because at least, if you did that, something in the world would change.
The petition? Not so much would change. Okay I might laugh.
