If you are tempted into using them on the basis of their ridiculous statistics then you are SO moneysupermarket.com.
They claim 40% of customers saved up to £316.20? So by definition 60% of customers didn't save anything. That's customers, moving to them and then getting a worse deal.
And of the 40% that did make a saving the MOST they saved was £316.20. So that is supposed to convince me to bother with the company is it? Way to go!
And what about supposedly 'healthy' snacks? Barney cereals try and make their product sound better than your standard cake or biscuit by specifically stating on the advert that they have, and I quote; "healthy ingredients like flour, chocolate and eggs..." Really? The main ingredients of all chocolate cakes, biscuits and many chocolate bars? So desperate that you are quoting the staple ingredients of flour and eggs and selling them as the healthy option. Healthy? Relative to what exactly? Compared to the sugar also in there?
