why are bar codes needed on deodorant sprays?

[Pinotage]

Same as they are on other goods, to identify them at checkout

is it so the cashier and computerised till know the price of the item? - but that seems just TOO easy, am i missing something?

Just about everything has a bar code, so that it can be scanned at the checkout. For a lot of informatio about bar codes and how they are used, look here http://www.howstuffworks.com/upc.htm

As everyone else has said it's for pricing. But also the computerized stock level can re-order more when a certain number have been sold.

Actually everyones wrong, the barcode is there for the robots and aliens from mars to know what flavor the deodorant is.
