The Sony Xperia X Performance has been reduced to $299.99, its lowest price ever, at both Amazon and B&H for a limited time only. B&H has a timer showing that the price will only be available until the end of the day. Amazon is likely price matching, so if you were considering picking up the phone now is a great time to do it. B&H has all colours available at this price, while Amazon only has the White and Rose Gold colours at this price (at time of writing). All links can be found below.
