I have a domain that is about 1 year old and indexed in google and I bought some cheap Pr3,4,5 and some PR 6 linsk for some keywords. Now I rank top 5 for one keyword and close to top 10 for other. Before I was on page 3 for those keywords My traffic increased from a nadir 4.5 thousand visitors a day to over 8K a day So link buying does work information you can use
