Ok i just looked on WW online tracker, it says Alpen light 4pp for 45g, Alpen original 4pp for 40g, and 5g's of Alepn is just a couple of raisins so definitely worth having the good stuff!
I eat the no sugar one (which I quite like), and Asda's no sugar one, which is slightly less nice but about a third of the price. I didn't realise the points were the same!
I also made the error of presuming Philedelphia Light would be the same as Asda light cream cheese... oh no, it's got about double the points!
