One of my favourite eco-blogs, Inhabitat, is giving away a PILE of swag on their blog this summer.
Up for grabs: A Voltaic Solar Powered Backpack containing an Inhabitat T-shirt and tote bag; a Freeplay hand-crank LED Lantern inside a cool Inhabitat Tote bag, and a bunch of awesome Inhabitat T-shirt or tote bags.
You just need to be signed up for their newsletter to be eligible for the giveaways. More info and how to claim your prizes are posted here. Even if you aren't looking for swag, though, it's worth it to sign up for their e-mail or RSS feed - it's a great eco-blog with tons upon tons of news from all over. Check it out.
