Sceptical here too - check the SUGAR content suits you - I was disappointed when I tried a couple of them when on cut price at Tesco a few months back - way too sweetened for my taste.
I'm not too sure what you class as sweetened. Both the varieties I currently have (simply delicious muesli and really nutty muesli) clearly state that there is no added sugar, but that they do contain naturally occurring sugars. I personally wouldn't say they are noticeably sweet at all, though I would agree that they are not the nicest to eat and I find the simply delicious muesli particularly hard going sometimes.
I'm never 100% sure if Waitrose and Ocado have exactly the same offers, but looking at the Ocado website, I see that not all of the Dorset cereals are BOGOF, but that the ones that are represent very good value. For example, Dorset Cereals Berries & Cherries Muesli 800g is £2.11, buy 2 save £2.12. Obviously this works out at £1.05 per pack, which is undeniably good value.
