Never tried this flavour before, not the flavour I would normally go for either. The trouble with Walkers and many other foods items these days, they have changed their recipes, and not for the good I believe. Poor quality and more expensive. But hey, that is just my opinion for what it is worth LOL
Adding up the prices from the Costa menu, the value of each bag is just over £16 at full price. The sandwich is £3.30 and there are 5 cake items at £2.60 each.
