Hey Annie,

It's a good question. I've experienced similar issues with IP. The conventional wisdom out there says that IP is a better way to go just because it's really easy to clear your cookies and see the offer again. Though this may be something that is more prevalent in savvy markets like "internet marketing". It may not be an issue so much for musicians. I just experienced a lot of inconsistencies with IP because I was staying in various hotels while my wife was in the hospital. Every time I moved hotels the offer restarted, where as it wouldn't if it was cookie based. I'll personally probably stick with IP, but I don't think there is too much harm going either way. For 99% of the people, it's really just that first click that matters. Few people will have multiple people viewing from teh same IP, or be moving around during an offer. So you should be fine which ever way you go.
