Galaxy S3: The Carphone Warehouse

The best deal we’ve seen is available at The Carphone Warehouse. The firm is offering the Galaxy S III for free on a £36 per month tariff with a free Samsung Galaxy Tab 10.1, InvisibleSHIELD screen protector and in-car micro USB charger. However, this is only available to the first 1,000 customers to place a pre-order for a contract deal online or via the call centre so hurry to grab this one.

If you miss the deal you’ll still get a free Sandisk 32GB micro SD memory card, InvisibleSHIELD screen protector and in-car micro USB charger.

Those not wanting to be tied down to a contact can get the Galaxy S3 for £499 SIM-free.
