Not surprised.

Yahoo is definately a second-place runner compared to Google. And Microsoft is way behind also. I think the problem is - Yahoo doesn't know what it wants to be.. neither does MS.. Google knows exactly what it wants to be (ruler of the world - but not evil..)

As a hint - I've done better with PPC placement companies that feed directly into the Yahoo database. A bit of searching might turn them up for you.. of course that doesn't get your $299 back, and it's likely to cost more than $299 in the long run, but it does work, especially if you have a dynamic website with changing inventory.
