totallywicked-eliquid.com is having a 30% off sale right now. I just bought the 510 mega batteries (I actually just receive them today). They are supposed to last much longer than the regular 510 batteries. Since I just got them, I can't really tell you how long they've lasted for me. The kits are located under the "featured products".
I do own a few 510s (regular size batteries) already and I love them!

Just waiting now, so many places I want to try, can't wait!!!

Anyhooo, my hubby is confused with me...
He asked, "I thought you were going to quit? What's with all the new toys?"
