I am also a member of naturallycurly.com.
They had a few features of product giveaways. Not sure if they teamed up with companies like Kinky Curly, Hairules, Miss Jessies etc. or if they provided the products and/or gift certificates themselves.
For example, you can feature the Joico vaporiron, people can enter, and winners are chosen by random drawings.
You can throw in some T-shirts and free memberships too.
Thank you for listening.
