Pick up a pumpkin for free this halloween

You can get a free pumpkin from the UK's major supermarkets thanks to a new offer from cashback website TopCashback.

TopCashback is offering 100% cashback on pumpkins bought from Tesco, Asda, Morrisons, Sainsbury's and Waitrose, so long as it doesn't cost more than £3.

Simply head to one of the eligible supermarkets and choose your pumpkin. You'll then need to send a picture of your receipt to TopCashback via its Snap & Save service. You can do this on your computer or using the TopCashback website. For more on how Snap & Save works, read TopCashback's Snap & Save shopping tool reviewed.

Then it's just a case of waiting. Cashback can take up to seven days to display as 'pending' in a member's account, then up to 30 days to turn 'payable'.

The offer is valid from 11am on Friday October 24th until Friday 31st October 2014 or until the 5,000 pumpkin limit is reached.
