If you own a Blu-ray player and a set of eyeballs, you absolutely, positively must add "Planet Earth" to your library. I insist.
This four-disc BBC documentary series has a list price of $99.99, but Best Buy has "Planet Earth" on Blu-ray for $24.99, plus sales tax in most states and $2.49 for shipping. (You can save on shipping by heading to your local Best Buy brick-and-mortar, though I'm not positive the price is the same in-store.)
Another option: Amazon also has it for $24.99, with no sales tax, but you'll need to to score free shipping.
I've written about "Planet Earth" before, and there's a reason I'm pimping it again: it's awesome. Dazzling. Jaw-dropping. I first watched it on the Discovery Channel a couple years ago, and almost instantly decided I had to own it.
(Sadly, I paid about $70 for it--and that was for the HD DVD format! I've since replaced it with Blu-ray.)
Narrated by Richard Attenborough (not Sigourney Weaver, who lent her voice to the version that aired on Discovery), the series' 11 episodes take you to oceans, jungles, deserts, caves, rainforests, and other remote parts of the planet, where you'll see breathtaking environments and wildlife. You don't have to be a nature buff to enjoy this; you just need a heartbeat.
As an added bonus, this version comes with 90 minutes' worth of extra footage that wasn't shown on TV.
Honestly, I can't recommend "Planet Earth" highly enough. This is $25 extremely well spent.
Bonus deal: If a measly 1TB hard drive won't satisfy your storage needs, today's your lucky day: Dell Home has the Iomega Prestige 2TB external hard drive for $79.99 shipped (plus sales tax in some states). I don't expect inventory to last very long, so act fast if you want this mammoth storage monolith!
Bonus deal #2: Speaking of storage, Amazon's new Cloud Drive offers 5GB of it to anyone with an Amazon account--no strings attached. But you can bump your free Cloud Drive account to 20GB by buying any album in the Amazon MP3 store--even those priced under a buck!
