I am just giving you the heads up, for anyone who buys energy bars for races.

These bars are being sold in Home Bargains for 19p each, i am sure i have seen these at £1.30 a bar, so if you do buy these type of things, and you have a home bargains near you, go get some!
They are £1.09 each on this site
It taste very much like a flapjack.
