Case-Mate phone cases for the iPhone 13, 13 Pro, 13 Pro Max, and 13 Mini drop by 30% when you apply the code CASE30 during checkout at Case-Mate. Shipping will add $7 to orders under $35. Some good picks are the pictured Rifle Paper Co. iPhone 13 Case in Garden Party Blue that drops from $45 to $31.50 and the Cute as a Dumpling iPhone 13 Case that goes from $40 to $28. Since all of the iPhone 13 cases are brand new, this is the only discount we could find for either case. If you're trying to meet the free shipping threshold, add a Glass Screen Protector to your order from the "Frequently Bought Together" menu on the product page since they drop from $30 to $15 when paired with any iPhone 13 case order. Sales tax is charged in most states.
