No more Vitality Rewards

Suddenly, those products where we would get a 50% saving on the price, do not have the Discovery Vitality logo on the shelf price. Instead a "B+" reward program is attached. Also, those products that were discounted with Vitality, suddenly do not appear on the pay slip and neither do we get a discount. Does this mean that Vitality no longer applies? If so, we would need to move to Clicks who support the vitality discounts. Why change something that works, or run the rewards concurrently, surely?
