Okay so I like to enter contests online (I know I'm lame). I just got a knock on the door and it was fed-ex with a package that needed to be signed for. The prize? This dvd.
Last fall I won a different dvd that needed to be signed for (retails around the same price), and of course I wasn't home so I had to go a fed-ex location to pick it up. I've had prizes worth more than that, hanging out on my porch all day, no signature needed.
I first found some through www.online-sweepstakes.com, and from those blogs usually found links to others. I follow them then through gfc or email and see when they have giveaways.
Sometimes there will be blog hop's, where each blog links to a bunch of other's and it makes it easy to find giveaways that way.
This is an example of a blog hop. Fall in love with fluff. It can take time, but I only work part time and so rather than want to go out and go shopping or spend money this is what I do. Or I do it while we are watching tv at night. I've managed to us save money (because I try to win things I know I can give as gifts, or things that we can use when we have a baby).
