Although I am a PLR seller myself, I also buy a lot of PLR for my own niche sites. In the beginning I would search for free or very cheap PLR, usually from wholesale sellers. But every single time I would find myself really disappointed, until I learned my lesson.
Those packs of 1,000 of articles for 99 cents have no value whatsoever. The articles are either poorly written, with grammar and spelling mistakes-or just plain wrong. When you find something even remotely salvageable, you bet it has been used to death on hundreds, if not thousands of sites. This overuse unfortunately renders the articles practically worthless.
What I do now is to shop on smaller sites. Those so-called “Mom & Pop” shops. They are a little more expensive, usually around $1 a page. But even so, it’s a steal when you consider the costs of hiring a ghostwriter or the time spent on researching, writing and proof-reading.
These sellers will usually take on requests for new packages-so let’s say you like their writing style, but they don’t have that pack of acne plr you want so much. Simply look for a form where you can submit niche ideas (usually on the sidebar)-they will most likely consider your request, specially if it’s a fairly common niche.
