I also purchased my cameras from Best Buy just for the extended damage warranty. Glad i did. I was out at night playing around with a tripod, stupid me, temporarily set the tripod up to grab a flashlight, which was just out of reach. Long story short, I didnt spread the legs of the tripod sufficient enough for the evening breeze.... *BANG*, tipped over, lens down on concrete (7d + 28-135mm).... Amazingly, the camera was completely fine, the lens, physically damaged the outer ring (in half) but it still worked! I ended up just using it as it was for some time, but was never happy with the focus & after being annoyed that my lens caps barely would stay on. I decided to send it in. It was sent to adorama (i believe) through best buy. It took 2 weeks, but came back fixed, cleaned and calibrated; no charge. Im grateful, and glad i actually got to cash-in on one of these services.
