And to add more, to find good feedback on items too that are for sale.
Other forums might post deals on stuff too but usually the people are just normal stupid shoppers. They don't know much about tech so that's why hardforum (with mostly smart tech people) is good for getting deals on good items+avoid buying junk items that are also on sale.
I visit the hot deals forum because I like the fact that I can find deals, nevermind that I didn't need another 2TB of HDD space, or a new video card that is barely better than the one I have, I just need to confirm my geekiness and than have my wife yell at me later until I buy her more points for her MMOs...
Great deals, I check [H]otDEALS more often then I check my email. HAHAHA. I've found some awesome deals that I've taken advantage of and become aware of products only because of [H]otDEALS!
