If you've been dying to get your opinion on a green product off your chest, now's the time to do it. Monday 7th April at 9am GMT is the final deadline to write a product review on SmartPlanet and enter yourself in the running for March's chance to win a bottle of organic champagne. Don't worry, you'll still be able to write reviews later, but this is your last chance to get in on March's competition.
All you have to do is click the 'write review' button when you're reading one of our existing reviews, or -- if we haven't reviewed the product yet -- add a new review. For some examples of reviews written by other SmartPlanet readers, take a look at this one on Acorn House, this one on Tesco's Fairtrade t-shirts, or this pull-no-punches one on The Body Shop's Shea bath and shower cream.
Next week we'll big-up the three funniest, most helpful and insightful product reviews from March's bunch, and get the champagne in the post.
In case you're wondering -- the tipple in question is a biodynamic Champagne Carte Rouge from organic vino experts Vintage Roots.
Update: we've extended the deadline so you've got the weekend to add your reviews!
