Here are some sites that I like, and who also are willing to pay me a small finders fee if you sign up for their service or buy products through them. You can get good stuff, I can get some money - sounds like a win-win situation.
I use Firefox and the Google Toolbar. FireFox provides a product that is at least as good as Internet Explorer, but doesn't seem to be as much at risk from hackers as Microsoft products are. The Google Toolbar adds options like Popup blocker, a search bar, spell checker, and more.
Google Adsense is a service where I allow Google to place ads on my web site, and in exchange I can make a small commission. I use this on my personal Blogs. I haven't made any money yet, but figured it can't hurt to try.
I am set up as an affiliate with Amazon.com - which means that if I refer someone to Amazon and that person buys stuff there, I get a small commission. The price you pay is the same as if you went there yourself, so feel free to click through this link to buy stuff (helping me while you do your regular shopping).
