well I guess that is that ..For the record I will be finding another vendor..the first time I called on the (order before) I called to make sure the mege dual cartomizers that I ordered fit the ego t pass thru because they do not fit (ego lcd ) and I am straight from an ecig pen device..I am aware, but not experienced about 510 threading.. The man said he didnt know any details about my order.. I say ok what I really want to know are the ego megas 510 threaded He said "whats 510 threaded mean" the guys name is Tom he is the other number on her business card.. Like I said they take advantage of people that are new to vaping..Anyhow off my soapbox for now. Caveat emptor Jason
For what it's worth I am also new to vaping and have had great success dealing with Eric Gormly at discountvapers.com. He is the owner and has very competitive prices. He also answers all the questions I have emailed him, usually within minutes and is very honest
He stands behind his products so you should try giving him a shot.
