It hasn't worked well for me. And I 'sacrificed' a product but honestly I still had some stock to sell for that product and I couldn't tell whether AZ had done anything at all to that product. I just had to send them some stock, and I got access to AMS. But fair to say that either I'm doing AMS poorly, or it just isn't really helping my sales much at all. I think I probably need to read up a bit more about the best way to do AMS and then give it another go, but I'm not seeing it as a great way to do PPC because it costs money and the return is poor. AZ Sponsored Ads get more sales for me though I'm better versed in PPC than AMS. As Danny says, it just depends on the niche and products I think. It's not a one size fits all program in my experience.
