Register with your email (or a fake) and get a coupon for $20 off $100 or more at Cabela's. If you can ship-to-store to save even more. It's possible to sign up with multiple email address and get multiple codes (just have to use them 1 per order). Just picked up 2k 223 bullets for reloading and some 223 rounds as well.
