I've been informed by a friend that Best Buy will be selling Black Ops for 24.99 on launch day only. Stock levels are high so there shouldn't be a great urgency to cue up at 9am.
My friend has no reason to make up such a deal as she's been spot on with all previous tips she's given me. You'll be able to see from deal history.
She's said that the deal will be available for launch day only and active at all stores.
Also said Kinect stock is awfully low at Best Buy with single figure solus units available with around 15 Kinect/console bundles available.
