BestBuy has Sony Xperia XZ on sale for $ 449.99 but after applying 10% off coupon from below post it comes down to $ 404.99. If you use ‘Visa Checkout’ as your checkout option, price reduces to $ 379.99
This is the lowest price for this phone ever if you can reproduce. If you have not received any 10% coupon from BestBuy, you can get one from above thread trough trading with Amazon GC(again YMMV)
