KIR Ammo has discount coupons good til the end of the year - $15 off $199, $30 off $399, $45 off $599. As a plus you can add the discount on top of sale prices. They have PMC .223 Rem FMJBT 55 grain on sale for $10.49/box of 20. If you order at least 20 boxes to make the $199 minimum for the discount coupon (AND free shipping) that comes to $9.74/box of 20 or .49 cents per round out the door. Historically not a great price but in the current market that's about as good as it gets. Plus, they don't charge sales tax to any sales outside of Texas.

I've done business with KIR before and I highly recommend them. They're really fast getting orders out and the customer service is great.

Move fast, there's only 142 boxes left in stock as I write this.

Price has come down to $10.25/box. Coupon codes are still good until the end of the year. Order at least 20 boxes to get the free shipping and with the coupon code comes to $9.50 per box shipped, and with no tax. When you use the coupon code this is the lowest price for .223 on Ammoseek (for sites that offer free shipping).

Ammoseek shows AEammo having cheaper CPR 5.56 with free shipping: https://www.aeammo.com/products/ppu-ppr ... 11-75-5666
Not saying this price is out of line with the current insane market, but it's not correct to say that the KIR price is the lowest free shipping deal on ammoseek.

AE Ammo charges tax, whereas KIR Ammo does not. So I'm calculating the PPU from AE at $0.523/rd delivered, and the PMC from KIR at $0.475/rd delivered (with coupon code).

That's not bad, I just got an order in today from https://www.ammojoy.com/ , PMC M855 for exactly .50/ round delivered.
