VideoJug has been around for a while, but it's only been recently that I've discovered the genius of it.
For those not familiar, it's a video site packed full of tutorials. You can learn how to do pretty much anything just by watching their videos. From how to ace an interview to erm..kissing. And it's free. There's a great iPad and iPhone app too, so you can have it on the side when you're using one of the cooking tutorials.
Not only does it save you money on expensive courses, but some of the videos teach you how to make things that would normally costs a lot. Like this guide to making invisible shelves (which I've seen selling online for quite a bit more.)
Ever used VideoJug?
