I did not know where to post this but I just went to the Brentwood, MO Best Buy and purchased a Macbook Pro Retina 13.3 256GB Open Box for 897.99. The price was 1,243.xx and then they took off 20% and then I used a birthday 10% off coupon to bring the price to 897.99! I had gone in asking about an unadvertised sale on the Macbook Pros that are $200 off right now in store and the salesman said that they are running a special this weekend only for an additional 20% off all open box macbooks. I assume because the new model is being released soon! I bought it as $600 bucks off was a sale that will not be happening soon on the new macbooks. Here is the model link.
I would go in and ask about the deal or at least call about the deal if you don't want to drive there (i know the #1 rule but this is def YMMV and was a manual override so it may not be at every location) However even the manager mentioned the promotion so I thought I would mention it here so maybe others could benefit.
