Rewarded Surveys have a new product to test. Just register with them and confirm your membership on their welcome e-mail. Once you've signed up you'll be eligible to test loads of different products.
This month they have a couple up for grabs including some natural deodorant. That's not all though - products are regularly added.
On top of product testing you will also be invited to complete regular surveys and you get points for doing so which can be redeemed for Amazon gift cards.
Unfortunately, the offer you were looking for has now expired. Sorry!
