What are the cheapest T18/T22 coils available? (I couldnt put *What* in the title because it was considered an extra tag?) Im a relative noob to vaping (6 weeks) and I live in Western Australia. Recently I bought 5 boxes of Prism T18/T22 coils at $9 each but I cant remember from where? Ive got friends who want to take this evil habit up themselves so I want to get them some cheap coils as well, any suggestions? The USA is out of the question because of the postage rates.
