Seriously -one thing I guess would happen though, is that traders would profit from rounding up their prices, I.e. no more of this £1.99, etc.
What I'd like to know is how petrol stations can charge prices based in fractions of a penny, E.g. £1.32.9p per litre - I've never seen this anywhere else how come they can get away with this??
