The following email went out to Yahoo! Search Marketing (Overture) customers;
Dear Sponsored Search Advertiser:We’ve listened to your feedback and are happy to announce that we’ve eliminated the $20 monthly minimum spending requirement for Sponsored Search. Previously, all Sponsored Search advertisers were required to spend at least $20 a month in click-through charges. Now, you can choose to spend as much or as little as you like, with no minimum to meet.
Thank you for being a Sponsored Search advertiser. We appreciate your business and hope this change makes advertising with us even easier. As always, we value your feedback, so if you have any questions please contact us using the support request form within your account.
Sincerely, Your Partners at Yahoo! Search Marketing
YahooSarah posted a thread at SEW forums to make the announcement.

FINALLY!!! Way long overdue. But then again if you are not spending over $20 you ain't doing much....

In the UK we still have £20 minumum, when asking why they said, "clients that spend less than this amount, are not commercially interesting for Overture". This is irrespective of previous spend or potential future spend.
