Axill is an affiliate program that pays its publishers daily on reaching the threshhold payment limit. Now, which other program does that? There are a large number of campaigns available to choose from, including a huge inventory of only-email and only-zipcode offers. Incentive allowed campaigns are also available but Axill provides no way to track the sign ups. So pretty much that option is useless. If you are looking to try out different offers on your site, Axill gives you the flexibility. And it is also known to pay its publishers. So there is no fear on that score also. So go ahead and try this affiliate network.
