out of stock TDK LoR ST-600 USB Gaming Headset "PC Only" - $5 with Free Shipping from Dick Smith
This was posted 1 year 1 month 14 days ago, and might be an out-dated deal
Saw someone mention this on Whirlpool, so I decided to check it out myself. They're PC only, so they're no good for Xbox or PS3 users. I don't know how good these are sound-wise, but TDK is a good brand and $5 isn't a lot of money, so even if they're absolute rubbish, it's no big loss. They'd be more that good enough for Skype/Msn.
It's my first bargain submitted here so be nice. Please don't start a Dick Smith flame war or anything.
Edit: Turns out that Dick Smith have started their online sale a day early, so there's a whole heap of discounted games as well.
Update: Deal has expired, so it's been marked as such
