The Product Review Place or MomBloggersClub are good. There are a LOT but some are better than others. You can even go on the ones that I mentioned and asked other people which ones they use. You kind of have to network with other bloggers initially. Once you get a good system down, you might even get PR pitches.
Re: I have a question for the bloggers who give away or review things.
What sites are there for mom bloggers?
