1. Yes, its possible to get a satisfactory deal from TigerDirect. It's also possible for me to win the lottery. So what does that prove.
2. Reseller ratings can be biased. That seems to be a matter of opinion, but hey if you feel that way, so be it, I won't try and change your mind. However, if you will scoll up a bit, you will notice that the BBB has unresolved complaints about tigerdirect, this isn't reseller rating or bizrate, or anandtech...this is an agency set-up specifically to deal with businesses who try to screw their customers. The fact that they have complaints means that they (the BBB) contacted tiger direct about claims filed with them and did NOT recieve a satisfactory explanation OR resolution to the problem. That tells you all you need to know.
No one's saying you can't shop there if you want. Just buyer beware....
