I ordered 2 tanks and a bunch of cartos from them and I made a mistake on my order. I called smoktek and he told me he was just boxing it up as we spoke.It had been like all of 10 min since I placed the order. The man I spoke with was very polite and helpful. I got a shipped out E Mail within a few min from talking to him. I will definitely be going back for more supplies. Thanks for the great service smoktek. It's nice to have people look out for you and treat you kindly when you are new
