We check prices every month and for Best Buys we give the cheapest widely available high-street price we can find. If we can't find the product available on the high-street, we give the cheapest widely available on-line price. For these reasons, the price you see here may differ from the cheapest price you see on Which? Shopping, where you will find online prices that are updated daily. Prices for products that aren't Best Buys are a guide to what you should expect to pay. Prices quoted for Phone Applications are the guide price for the application plus any accessories required to run them and not the phone. We advise you check with the provider for the latest deal.
