With witches, werewolves and vampires stalking the streets, Halloween is frightening enough already. And that's before you check your bank balance.
But the cost doesn't have to be scary.
With the spookiest night of the year right around the corner and Bonfire Night following shortly after, we take a look at ways to keep costs down without missing out on the fun.

Waitrose was twice as expensive as its rivals, with medium pumpkins on sale for £2 each.
Asda doesn't sell medium pumpkins online, only large ones for £1.50.
Tesco was the only store that had pumpkins on special offer, with large pumpkins priced at £2 each or two for £3.
Keeping tricksters at bay doesn't have to cost a fortune. Especially if you keep your eyes peeled for sweets on special offer.

Marshmallow brains, gummy eyeballs, and even candy blood are all available at low prices.
For healthier snacks, Tesco currently has 'easy peeler' clementines and mandarins on special offer at 79p for a 600g bag.
