Sol's 'Writing Resources' contains a document entitled 'PUNK-CHEW-AY-SHUN'. At the end of the 'The Comma' section it states:
Do not use a comma before the first item or after the last item of a series:
The treasure chest contained three bottles of rum, some gold jewellery and five thousand pounds of silver. [WRONG]
The treasure chest contained three bottles of rum, some gold jewellery and five thousand pounds of silver. [RIGHT]
I can't see any difference between the 'wrong' sentence and the right 'sentence'.
