In the past week, I've had two shopping experiences where I got a better deal online (with free shipping) from stores whose physical location is less than five miles from my house.  In other words, I saved money by shopping online as opposed to going to the store.  I don't quite understand how this is possible, but I'm not complaining.  It seems like there's a slightly larger environmental impact by getting things shipped directly to my house, but other than that there's absolutely zero downside.
