I just thought it would be a good idea to have some sort of merchant rating system. To indicate how good their service is.
For instance - Play.com have always been very good with my orders. So I could rate their service hot. But then other merchants such as CDiscount.co.uk have been widely overselling and then ignoring customers, so I could rate their service as cold.
It would be useful to know a hot/cold score before purchasing from these merchants.
