Best Buy offers 10 Best Buy Reward Zone points when you visit any of its retail locations and "check-in" via its mobile app for iOS or Android. (Not a Reward Zone member? It's free to sign-up.) That's the first free Reward Zone points deal we've seen since July, when we saw 12 points for answering six trivia questions. Check-ins are limited to twice a week, and are only rewarded if they occur 24 hours apart.
