Vistaprint cuts 50% off custom iPhone and Samsung Galaxy cases via coupon code "FREESHIPX". (Click through "Phone Cases" under the "All Products" tab to shop these deals.) Plus, the same coupon bags free shipping on all orders. That's the best discount we've seen on these cases from Vistaprint. (It also took 50% off in November but lacked free shipping.) You can create cases for the iPhone 4/4S, iPhone 5/5S, Galaxy S3, and Galaxy S4. Coupon expires March 2.
