Have you worked with AvantLink before fro affiliate marketing?
We have not worked with AvantLink before but I suspect they are not all that different from two other affiliate marketing companies we have worked with, Commission Junction and LinkShare. Please let us know if you'd like us to look into AvantLink for you and what it would take to implement it on your website. A quick search reveals they have a plugin for WordPress, which would probably make the implementation fairly easy:
Again, please let us know how we can help. Thank you.
