If you have kids, I'm sure you're like me in this respect. You go through bazillions of batteries. Until you realize that raiding Costco every other weekend just for batteries just doesn't cut it anymore.
No more batteries for me (yeah, right). This guy in Hawaii sells rechargeables cheaper than normal batteries in some stores. My best EBay experience by far.
Other people want $2 per cell, which is not too bad either, considering you can pay up to $4 per cell in the store.
Anyway, this is just my way of saying thanks again, Sheung!
