Walkers has extended its 39p pricemarked range to include Monster Munch roast beef and pickled onion.

The new additions join existing variants Cheeseballs, Snaps, Frazzles, Twisted and Chipsticks.

Pepsico field sales director Matt Goddard said: “61% of shoppers think that pricemarked packs in independent local retailers offer better prices than the supermarkets. From January 2015, we will also be supporting the Walkers 39p value snacks range with a ‘3 for £1’ promotion to help increase basket spend for retailers whilst also building shopper trust to encourage repeat purchases.”
