Not sure if this helps or not but I've checked the "eat out" book and it doesn't have debenhams products in but there are a few other similar ones which I've listed.....
Caffe Nero bio yogurt 5.5 points
Boots shapers blackcurrant granola 3.5 points
Eat yogurt and granola 6.5 points
I'd go worst case scenario and point 6.5 based on the "Eat" product.
