McVitie’s has added three ‘2 for £1’ price-marked packs (PMPs) to its on-the-go cake range. The products are available in six variants including McVitie’s Chocolate Hobnobs Slices, McVitie’s Milk Chocolate Digestive Slices and McVitie’s Digestive Caramel Millionaire Slices. As part of the re-launch, a smaller 12 pack case size with a longer shelf life will replace all previous 24 and 18 pack cases.
