We've got two free magazines for this post, Stuff and Seed. First off is the free Stuff magazine subscription that you can get simply for using the coupon code freestuff. I've never had this magazine before, but I just signed up for it so I'll let ya know if it's any good.
The second freebie is a free Seed magazine subscription. I'll be honest, I thought this was an adult magazine based on the name when I first saw it, but apparently it's about how science and society interact and it talks about hot topic issues, such as stem cell research, global warming, public health, capital punishment, etc. You need to use the coupon code freeseed to get it free and again, I'll let you know if this freebie is any good once I get it.
