It would be nice if the Windows Store allowed developers to reply to reviews. There is a review related to small live tiles on Bitcoin Tracker, but the problem is that Microsoft created no API for that.
Got my oil changed with the car wash as well. After waiting an hour they came and told me there were 1600 dollars worth of parts needed. I told them to change my oil. I left, got home and realize they broke my antenna. I had someone else look at it and they stated there were no problems ($1600). I drove it for a month and it turns out there was no oil in my truck. Good thing I caught it before the engine seized.
