I just stopped in to a Pilot gas station a minute ago and noticed they had two starter kits and replacement carts for sale. For a moment i thought about buying some carts to see how they fit my Puresmoker Penstyle, but then I saw the prices. They want 20 dollars for a pack of carts! I'm not sure how many carts that gets you but it should be a bunch for that price. The Starter kits were $70. I paid for my gas and went on my way. I'll stick to purchasing on the internet.
