Howdy, In SEO industry so many ways days develop back links. After recent google update we avoid spammy links so still working paid links or not.I have confused lot paid links use or not.
now a days not good paid link for any website create natural back link by articles, bookmarking, directory, Etc. are good benefits give your website.
If you are buying links at only PR site and you are not checking the relevancy, back links, uniqueness then this is really useless for your site. Take care about this.......... Best of Luck
Quality paid links never harm your website. But, you will have to check quality and it has to be relevant. Now a days Google focus ing on quality guest posting and quality paid links.

If you could afford it, then there is no harm in having them. If your website is not getting any traffic at all, then it is worth trying it. Although, it may not do any good to your website. Better if you opt for Google Adwords program or affiliate like in this forum itself which could draw you genuine traffic and result in business leads.
totally agree. buying/sellign links is prohibited by Google. If they catch your site, or someone report it to Google (fyi, Google provide this feature recently), if your site selling/buying links, then your site will surely be penalized.
