I got the introdutry offer which came with a 2 page contract for an additional $109.90 which I got the idea that it would pay for an additional 30 day supply of cartriges. It did not.
But after 6 weeks I had another $69.90 debited from my account after being without cartriges for a month. I had in the meantime found that no other cartriges available were compatible with Direct E-cig because of the thread diameter.
I did however find E-cigs locally available for $12 with atomizers built into the cartrige. These are compatible with most other brands.
Direct E-cig is a scam to seperate you from your money.
