Let's be honest: the Xperia X was kind of a ripoff at its MSRP of $549.99. It's a solid mid-ranger, but that much dough for a non-flagship? Come on. A few months back, this Sony smartphone got a price drop of $50 to $499.99. Now, numerous official retailers have dropped their prices to an even more palatable $449.99, and BuyDig is also throwing in a Lexar Class 10 128GB microSD card.For $450, you get a 5-inch 1080p display, Snapdragon 650, 3GB of RAM, and 32GB of internal storage. On the optics side, you get a 13MP front-facing camera (for all those high-resolution selfies) and a 23MP rear-facing module. Keep in mind that unlike its bigger brother, the Xperia X Performance, the Xperia X is not water-resistant, so don't go swimming with it.Multiple retailers have the phone at $449.99; however, if you're interested in the free 128GB Lexar microSD card, you'll have to purchase from BuyDig. There are still reasons you'd want to buy from other sellers though; maybe you're an Amazon Prime member and want to get free two-day shipping, or maybe you live near a Best Buy and desire the ability to pick the phone up locally. You can also choose from B&H and Target. Every store is carrying all four colors (Graphite Black, White, Rose Gold [it's pink], Lime Gold).Check the source links for each retailer's Xperia X listing.Source: Amazon, B&H, Best Buy, BuyDig, Target
