I just lucked into 5 boxes of the Federal .223 55gr 100 round value packs at Walmart. $37.99 a box. That is cheaper than I have been finding PMC. I am a big proponent of patronizing my local gun shop, but saving over $.12 a round is important too!
It pays off to do random drop ins when driving by stores that have ammo for sale. While I was there, somebody was buying the last of the 9mm value packs that were in the case... However, they had more stock than I have seen lately.
Autrey's

in Fayetteville Ga is starting to have a lot more ammo in stock. Lots of PMC and Wolf. Hopefully the price will start coming down as the supply returns.
