After you've had your Christmas dinner, there's nothing more relaxing than kicking back and indulging in some chocolate whilst you watch the mountain of festive programmes on the TV.

Supermarkets are already offering a special price off tins of your favourite selections; but you need to fully think of the cost. Sure, £5 for Quality Street is fantastic, but when you buy this early are you really going to stop yourself from pinching one or two before the big day?

Soon, £5 could turn into £20 and that's a lot for chocolate - no matter how good it tastes!
