If It Looks to Good to be True

My DH saw a promotion on a newsfeed for Amazon last week for a box of 71 bars of chocolate - Breakaway, Yorkies, Toffee Crisps, Blue Ribands and KitKat (2 finger). They were offering the box £16 for a limited time now it's £25 as I have just checked. We buy a couple of packs occasionally so I did the maths and worked out how much it would cost to buy the packs from the supermarket and we are astonished. The 71 bars would cost £13.97 if bought from any supermarket. Breakaways have actually been discontinued according to Nestle but might be available in some places.
It just goes to show that it pays to price things like this before buying.
