It's $29.95 /mth which is $359.40 /year (in US Dollars) for access to over 2000 newspapers and magazines, or so it says on their web site. Though to be honest it is clear as mud to me what you really get for that subscription fee. It looks like maybe you get a certain number of downloads/credits per month to download newspapers but they don't seem to say anywhere I can find what that number is.
From their web site:
"For the price of a single newspaper subscription, receive access to over 2000 full-content newspapers and magazines every day, and help save our forests. "
I think I will stick to using Calibre for the little bit of newspaper reading I do, its free! and also saves our forests
