Go to http://www.prweb.com/ I think they are still at $200 a submission, but I was too lazy to check.
I've tried several free press release services, i must say they arent very effective. I didnt see any results from them even after a few weeks. I guess you just have to pay if you want results..
Try www.free-press-release-center.info You can set your anchor text for each press release using a choosen keyword. Thanks, Gary
Also one other thing about not seeing "any results from them even after a few weeks." when using a free press release service. The key is in writing a good press release. If you write a poor press release you can pay hundreds of dollar but still you won't get the exposure. Your press release needs and angle and needs to be relevant. Ta, Gary
