Thread title: Cheap rechargeable batteries at

There is a 5% off coupon there.
Can't find the AT thread, I know there was one.
I just placed an order last night. $100 for a $20 kit for a friend, $30 for the best charger they have (pulse charging, full discharge, etc), $30 for 24 AA and $20 for 24 AAA, and they threw in one of those quick chargers free with a $95+ order. Received confirmation immediately and my shipment shipped last night. So far so good. The price is ~1/3 to 1/4 of in-store prices on rechargeables.
Re: batteries dying - Your better off using a high quality slow charger when you can, and saving the quick charger for when you're on the road or need it quickly. I just ordered enough that I would have enough extra that I can afford to use the slow charger. Although I have a feeling 24 AA won't last that long. Heck, remote controls alone is going to chew up half of them.
