I have just 2 links left available on a pr6 web app. The website has been featured on the Today Show and on numerous tech blogs (including Lifehacker, Mashable, ReadWriteWeb etc.)
Your link will be placed in the footer and also on the sites blog.
This is both a high traffic and PR link placement.
Price Per Month: $35 (big discount for multiple months - and I'll throw in a 3xPR3 Links on other sites if you buy 1 year).
PM for site details.
