TODAY is your last chance to win a coveted Blue Peter badge or £314 worth of beauty products in this week's reverse auction in aid of Maggie's.

It's not just any old Blue Peter badge, it's a special gold 50th anniversary edition.

Former presenter and Maggie's patron Janet Ellis donated it for the Post's weekly reverse auction which is helping to boost the £500,000 appeal for a cancer caring centre in Nottingham.

The badge can be yours if you make the lowest unique bid.

This week's other prize will help one lucky lady to keep looking young and beautiful.

We have £314 worth of Rodial beauty products up for grabs.

Rodial is a favourite of celebrities including Jennifer Aniston, Scarlett Johansson, Paris Hilton, Victoria Beckham and Kristen Bell.

There are four items: Glamtox SPF18, a daily moisturiser hailed the non-invasive alternative to botox; Glamotox Night to reduce wrinkles, tighten and tone, and restore moisture; A-List Cleanser and Glamtox Peel, a 'ten-minute facelift' to reduce fine lines and fade age spots.

Here's how to enter. In this auction, it's not how high you bid, it's how low. If you are bidding for the Blue Peter badge, text EP BADGE to 65100 plus your bid in pounds and pence. If you text EP BADGE 5 you will have bid £5. If you text EP BADGE 0.50 you will have bid 50p.

For the beauty products do the same but start your text EP RODIAL. If yours is the lowest unique bid by the end of the auction, you win. So if lots of people bid a penny, and you are the only person to bid two pence, you win! All it costs you is the price of the text – in this case it's £1 plus your standard network rate – with all the profits going to Maggie's. The winner will also have to pay their bid.
