This site seems to be doing the rounds at the moment as the latest money-making craze:

The basic idea is that you sign up and create your own "shop" to sell items for EI42.com. They seem to be the usual internet referral company - giving you vouchers and codes for discounts for major internet retailers (such as Amazon, Argos, Tesco, Play.com, Lastminute.com, etc...). If an item is sold through your shop, they pay you a small part of the commission they make. Obviously, it's only a tiny amount but it only takes 2 minutes to register and set up the shop - beats the hell out of filling in online surveys and questionnaires to make money on the internet. Plus you can just leave it running, no fiddling or updating needed. There's also a referral system, so if you get other people to sign up to it you get a fraction of their commission when they sell an item as well.
Give it a bash and make some quick cash.
I don't think it's available outside of UK at the moment though.

Well, it's been a little over a day and I've logged back in to check how good this system really is. So far I've made £5.23 through their commission service.
Plus, it seems that they allow you to buy items online through your own shop. Which means that you get the commission back on anything you buy, so it's like getting a 5% discount on it. Not too shabby.
In case anyone's wondering, this it what the "shop" you create looks like:
