If the company provides you with a product to review in conjuction with the giveaway, make sure that you place a disclaimer statement. Mine says something to the effect: I was provided with a product for the purpose of this review. No other compensation was received and the views here expressed are my own.
This is my first giveaway!! I will have several more coming up. I am planning to change the comment section, but am scared of making any changes mid-giveaway. So, don't know how I'll figure that one out.
I'm still reading your review, but I LOVE your style. I like how you break things up with the brackets and I am totally going to copy your style going forward! That really helps the reader and I wish I had done that!
