We don't have any official confirmation of this, but there is a rumor floating around that on December 16th, Best Buy will drop the on-contract price of the Samsung Galaxy S III to just $49.99 for all major carriers. This is basically $150 bucks off the original subsidized price of the phone when it was released. The source of this rumor did not indicate whether it was a sale that would go beyond December 16th, so it could be a one-day only deal.
We will keep an eye out for you guys, but if you see or hear anything post it in this thread.
