Winchester is offering 25% back (up to $50) on most of their centerfire pistol ammo. .38 sp, .357 mag, .380, .40 S&W, and .45 Auto. Here's a link to the details.
I agree. My dad and I could always purchase .45 acp but it would have been nice in the 9mm too. Maybe 9mm is selling just fine for them so they don't need to add incentives.
