I got this in my email today:
From November 3, 2008, until December 31, 2008, Yahoo! will be making a seasonal rate adjustment by increasing the cost per click (CPC) by 25% in all categories.
Hey Yahoo, take your shitty Pay-Per-Click scam and shove it up your seasonal ass.
If there are any readers thinking about doing pay-per-click, consider this: Last Christmas, I made approximately $25 profit for every $300 I spent. Your time is better spent setting up the free Google-Base. Not as much traffic, but again, it's free. So is http://shopmania.com... for what it's worth. Also, drive ebay traffic to your website. When they ask you a question in email, be sure to respond off-system with all your website information... and tell them it's cheaper too.
