The MoMA (Museum of Modern Art, NYC) webstore is having a poster sale. They have a selection of about 60 posters for about $4 each (USD), and if you buy 3 or more posters, they discount each by another 30%. I've been looking for a cool but cheap (since I'm just gonna rip it off my dorm wall in May anyway) poster, and was very excited to stumble across this. You can't beat 3 posters for 13 bucks. Anyhoo, I'm getting these (I have varied tastes, as you can tell I think I'll put one up right away and save 2 for when I have my own apartment (which will hopefully be fairly soon). Here is a link to the sale in case anyone is interested.
