Nope, I don't do them. I've only heard of a few success stories regarding blog giveaways. I was contacted once about a review and giveaway. She wanted me to send two items - one for her to review and one to give away (she keeps the item she reviews). I asked what her blog stats were - number of followers, weekly views, etc. It was lower than my blog, and mine doesn't get very much traffic! I politely said no. I'm not into giving my stuff away for free like that. I hate to be a skeptic but I think some of them are just looking for freebies.
