Lightning deals include Plants vs. Zombies for $13.99 on Xbox 360, and several deals that have yet to be named specifically. We've got "guesses" after the break courtesy of Thrifty Nerd. We say "guesses" because, as repeat deals, it's not too hard to figure them out. Likely highlights include discounts on the DSi XL, PS3, and Vanquish. In addition, there's another whole list of "family-friendly" discounts today for day 2 of Amazon's "17 Days of Deals."
