With the 30th anniversary of the abolishment of the 1/2 p coin coming up i've always wondered why petrol is sold in .9 of a pence at the end. 
How can a product be sold with an amount thats not legal tender - minimum delivery is 2 litres - i'm paying 132.9 currently - 2 x 132.9 = £2.65.8??? or can you not dispense that accurately, have to be honest i've never tried!
Why not just call it £1.33 - i'm not stupid, if something is marked up as £19.99, its £20 - a penny isn't going to sway my purchase decision, and £0.001 is certainly not !
