Last week we posted a contest about a new skin that gives your device up to 70% more power in those times of need. Because the contest was such a great success, PowerSkin in offering BlackBerryOS readers 15% Off the BlackBerry Z10 PowerSkin! All you have to do is use coupon code NWBBZ10SM while in the PowerSkin checkout. Coupon is good until 4/15/13. I'm definitely going to be getting my hands on one of these!
