Low-calorie snack brand Crips 99Cals has bagged its first national supermarket listing.

The oven-baked wheat and potato snack, which its maker claims contains 70% less fat than traditional fried potato crisps, is rolling out to 300 Morrisons stores in sea salt & balsamic vinegar and mature Cheddar cheese & spring onion flavours. Packs (rsp: 49p) will be sold on a three-for-£1 launch promotion, with sampling planned at 100 Morrisons stores.

Fifty Tesco stores in the Midlands and 67 Waitrose stores already sell 99Cals.
