I wanted to thank everybody again for all your help in helping me purchase my first ecig. I decided to buy the 510 and purchased it from vaporbarn. The service was terrific and the juice is also great. I want to ask; however, if anybody knows where I can get the best usb pass-through for the 510 and also how to use it with a regular car charger. I was told this was possible but wanted to know how. Also, is there a good place to get a PCC, pass-through, and a good sampler pack all in the same place. I have only seen samplers at Johnson creek and was wondering if there were any other places that had them. Thanks in advance!
