The Boots meal deal enables shoppers to purchase a sandwich, snack and drink for a set price of £3.29 ($5.54) or two for £6 ($10).
“The Boots meal deal is a simple and highly successful offer,” the European snack major said.
McCoy’s, Skips, Pom-Bear, KP Nuts and Hula Hoops are the brands in the offer.
KP Snacks was bought by Intersnack From United Biscuits in late 2012. In December last year, it invested in a £16m ($26.9m) consolidation of its nut processing and packing operations.
