Free Stickers and 20% Discount from Ziraxia

Here's a really interesting promotion sent in by reader Stu from The Shiny Swine: when you sign up to get two free alien stickers (pictured below) Ziraxia will give you a 20% discount on your immediate purchase.

See, that's the catch there. You have to be ready to buy as soon as you sign up for the stickers because the discount will disappear if you leave and come back to the website.

Of course, if none of their t-shirts appeal to you, the stickers are still plenty of fun (and it's incredibly easy to cut off the advertising text on bottom).
