In regards to RFD, I don't know if you guys know of their alert feature?
You pretty much just put in a key word and any time someone posts a deal with your key word you get an email.
RedFlagDeals Topic Alerts
(You have to be logged in for it to work)
This has saved me time looking through the forums.
I needed a cheap monochrome laser printer and I just put in "laser printer" and I would get alerts for them.
Ended up buying one for $30 because of the alert as I don't check RFD daily any more.
And this way, you won't get suckered into buying something you see as a good deal.
