The AbsurdlyCool Freebie Finder does exactly what the title says, helps you find free stuff that’s… well, absurdly cool.
Freebie Finder is an automated free stuff aggregator. I’ve designed it to collect free stuff offers from top freebie sites, while filtering out most scams and referral pyramids.
I haven’t used it myself yet, but it looks promising. (Found via LifeHacker.)
