Eating cheap - discount food on the web

Today at work I was informed about the presence of the website Reduced to Clear (NZ) when one of my coworkers came in with a pile of chocolate to hand out. I didn't have a huge amount of time to check it out, but as well as lollies it does cover quite a few categories of groceries, and the prices look like they vary quite a bit - some close to what you might get in a supermarket, some quite a lot less. He said you have to spend about $40 to get free shipping, but it could be a pretty good resource if you're keeping an eye out for deals.
