You may be better off just buying those items on Amazon.com. 30% does not come close to covering the high markup that Sprint charges. My wife used to work at Sprint and she would show me the 30 dollar case they sold they paid only 8.50 for, and that same case was 6 dollars after shipping on Amazon.com. Same with the SD cards. Check Office Depot and Office Max, they always have SD cards on sale, you sometimes just have to call them and ask what their sale prices on SD cards are.
