Unit price errors

I find there are frequent errors in the unit prices, which means that all unit prices are untrustworthy. For example, I have just been looking at Aldi smoked back bacon at a price of £2.29 for 360 g. This equates to a unit price of 64p approximately per 100 g. Your unit price is shown as 6p per hundred grams; out by a factor of 10.
