Hello Harry, I asked a similar question the other day and one response I received was that pr news wire was the best of the bunch. I was looking at a few pr sites. Pr buzz which is membership based and only $300 per year with unlimited submissions. Pr wire which has a tiered level pay structure Pr news wire which is also tiered Online pr news which has a free submission and tiered level as well I would run a search on open site explorer of these to analyze them separately.

Thanks for your reply. PR Newswire does look pretty good although I don't understand the pricing? On the site it says it's only $195 if the user will pay all future payments by credit card - what does that mean?
