In addition to the big three AdWords alternatives (i.e. Facebook, Yahoo!/Bing ads, and Amazon), there are many smaller ones that still serve millions of impressions a month. One of them is Clicksor. It isn't the cheapest alternative because it has $0.05 cents a click minimum but it is a good one because its conversions are known to be excellent. If clicks are expensive for you, check the other forms of ads offered by Clicksor, such as popunders and interstitials that are CPM or mixed CPM + clicks.
