I saw that, but passed. Batteries are one of the few things that I'm likely over-finicky on. Not saying that's a bad brand, just that I'm not familiar with it and am not up for gambling on that quantity of an unfamiliar brand.
That said, I do like Woot and buy things from them semi-regularly. Just received a 40-pack of 8-gig thumb drives from them today for our business; paid $149.99 for forty of them. Several weeks ago they had a pretty decent deal on metal Type-1 gas cans and I snagged a few. (I hate the mass-market weird-spout gas cans that take three hands and a monkey wrench to pour liquid out of.)
