Walkers is extending its 50p pricemarked pack (PMP) range with the addition of Squares.

The new Squares PMP format will be available from the beginning of January and will offer an incremental sales opportunity for retailers.

According to a Him! PMP Report 2013, 60% of shoppers are more likely to visit a store if there are PMPs available and 55% say that pricemarked packs would make them switch from their preferred brand.
