Not sure if people here know about this: http://www.1-day.co.nz
Basically, everyday, 3 deals come up. There are limited numbers available, so the first in, first served. They have everything on here from food and drink to clothes, sports equipment...you name it. Once they're all gone in a day, they say sold out until 12pm the next day.
Sometimes, they have more than 3 deals in a day - some have 1 item that changes every 20 mins, sometimes its 3 items that change every 20min, sometimes they renew every time they sell out - but only for 24hrs, then you're back to 3 deals 1 day.
I've bought so many things I don't need from this site (ahem...10kg of easter eggs for $25 inc postage, and 24 bottles of V rings bells here!), and I'd recommend it to all of you too.
