ShareASale is like Commission Junction’s weird cousin. Where Commission Junction has lots of big, well established brands, Share-A-Sale seems to be the place to go if you are looking for niche products and offers that you would never see on Commission Junction. Another way to look at it would be Commission Junction has the kinds of offers you might see on primetime TV commercials, whereas ShareASale has the kinds of offers you would see on the home shopping channel in the middle of the night.
