Brownells is doing $40 off a $300 purchase (code NEL), $25 off $200 (code NEK) and $10 off $100 (code NEJ)

I just tried it on the black label, black pack rebate 45ACP ammo and it works. After rebate, after code, you can get Blazer Brass for $11.11/box shipped, if you buy $300 worth and add a $1 filler item to the cart.
