When the lovely folks at Ocado offered us the chance to give away free groceries for the rest of 2010 as part of shopping month, we knew we'd get a massive response. However, even we were bowled over by the sheer volume of you who responded to our shopping month survey in the hope of scooping the big prize.

In fact, more than 6,000 of you completed the survey and entered the draw, giving us some major numbers to crunch (watch this space for the very revealing results of the survey). However, there could be only one winner, plucked at random from all the entries, and she was a lovely lady named Rachel Graves from south west London.

Lucky Rachel was absolutely chuffed to bits with her win (well, who wouldn't be?) and was keen to point out that, now a fully fledged 10:10 sign-up, she's cutting her carbon like a champ.

"I'm completely thrilled to have won the competition," beamed Rachel. "While I hadn't heard of 10:10 before, I'd already been trying to reduce my carbon emissions. I'd turned down my heating and reduced my water temperature on my washing machine, and I've recently gone veggie, too!"

Thank you 10:10 and Ocado for such an amazing prize - I can't wait to start using my vouchers!

"I already drive as little as possible, and using Ocado will really help me there. I know there's still some way to go but I'm looking forward to getting more tips from 10:10. Thank you 10:10 and Ocado for such an amazing prize - I can't wait to start using my vouchers!"
