Yes and no, on the mail order idea. I get S&B for $6.70 a box shipped and you can get better deals if you look around. Personaly I prefer the S&B to Win white box because I find it cleaner, more precise and even a bit more consistent. I have "felt" Winchester to be less consistent in presures. Maybe it was just me, and I do admit that it is a pretty darn good deal for over the counter and small quantities. It takes buying 1000 rounds to get the price above.
