I've been a TigerDirect customer for years and always used the reviews to help me decide on purchases - that is, until I decided to post a review. It was a negative review about a product that I felt was crap and it never showed up. So I posted it again. It was very professional and to the point, without emotion. Still, it didn't show up. I tried a third time. Still no go. So I posted a whole bunch of reviews over ten or twelve items I had recently purchased. None of the negative reviews showed up. A bunch of the positive ones did, though.
After closer examination, and reading on other message boards, I learned that other customers experienced the same thing. This is when I learned that they (Tiger Direct) filters the reviews and allow only the positive reviews along with one or two loony negative reviews to be posted. I suspect they feel if they allow some negative reviews to post, this will lend some sort of validity to the reviews. And of course, customers will conclude upon reading the loony negative reviews, that the reviewer was a kook or too demanding.
I eventually learned that this was common practice among retailers, to filter and manipulate the reviews. All this time, I thought the review system was on the "up and up". The last time I was that let down, was when I learned that Tru-TV's "Repo Man" was fake. LOL! Now, I simply take reviews with a grain of salt. They are all manipulated in one way or another.
Just thought I would share that.
