I refill the carts (the type in which the atomizer punctures the foil) by taking tweezers and pushing the foil to the sides so that the hole is bigger. Then I squeeze 3-4 drops into the hole. I pick it up and cover the tiny inhilation hole on the bottom with a finger. I blow INTO the cart a couple of times to get the juice down in there and not pooled up on top of the foil. I give it a minute to soak into the filler. Then I pop it back onto the atomizer and vape away. It's important not to store it upside down...don't want to run the risk of the juice soaking the atomizer. I store mine on its side or stand it upright (with the cart on the bottom). I rarely have juice leak into my mouth. When I do, it's because I've overfilled the cart or forgot to wait a minute to start vaping again. 
Good to know about the atomizer prices. I didn't realize they were so much higher on ecignational. When the time comes, I'll have to hunt around elsewhere for a replacement that fits the Firelight.
