In time, I'll even give the liquid a try.
Shoot! I probably am not answering this in time for your order, but you should definitely get liquid. I only had my ecig a couple of days before I got a case of the "I wish I hads...."
When the carts were empty I KNEW they were still good. I just kept thinking back on the liquid and if I had some I could refill the carts and use 'em up. So I ordered some liquid. Best idea ever! Wish I'd had enough faith to do that to begin with. I saved all my partially used carts and refilled them when the liquid came in.
