Samsung Galaxy S3 Excellent Condition Like New -

I am selling a samsung galaxy S3 in white. Had the phone for about a month. It was an upgrade on orange but can easily be unlocked to any other network. I am going travelling so just getting a PAYG phone. Everything is in box and it is in New condition. I am open to reasonable offers but please bear in mind the retail price of 500 when making offers. Please send any questions. Thanks
