The BB I went to was super busy. I guess they were just interested in turning over inventory. The first one I went to was pretty quiet. I'd try the bigger and busier Best Buy's and avoid all the small ones.
Got really close to get a 6D at BB this afternoon.
The blue shirt was very helpful but a little bit suspicious about the printout coupon.
So for final requirement he ask me to show my email containing that coupon. Too bad I cant find it. Otherwise Im now a new happy owner of a Canon 6D.
Im gonna be more prepared next time.
