I would be interested in hearing any news on the rewards. I don't always check them, just look at my points in the corner, and could be missing out on some deals. Or not knowing if some have been discontinued, go in to redeem and find it doesn't exist any more.
The only rewards I've ever used were Starbucks, Amazon.com and Redbox. Those seem to be the only retailers I've ever seen since I've been registered for Bing Rewards.
We use Netflix for streaming some things but have been renting blu rays with Redbox. There's a kiosk very close to the house. And the app for WP8 works great for checking what's available and reserving it.
