This seems pretty good to make your own. I remember someone mentioning some designs they had on here before. I'm really considering making stickers beyond my own use given how cheap it is, especially in bulk.
I don't suppose LvMI would be upset if I used their imagery?
Ultimate bumper sticker that should be used by a mises.org poster:
IF YOU ARE RIGHT-WING, YOU ARE STUPID.
IF YOU ARE LEFT-WING, YOU ARE STUPID.
IF YOU ARE CENTRE, YOU ARE STUPID.
(And if you are a radical, don't worry, you are sane.)
Well, it would be more settle than that. Mainly some Rothbard and Mises quotes, maybe some LRC and LvMI designs, and some political, anti-state, designs.

I've been to the first two links and they didn't have exactly what I was looking for (I only found two that I thought of buying). There's not enough Austrian related stuff, and some of the stuff Liberty Maniacs has is too cartoony. I really like their stuff, but I don't need a "Hayek Is My Homeboy" sticker on the back of my car.
