SGAmmo.com has PMC X-TAC 5.56 on sale.
PMC X-TAC 5.56 LAP $7.99 per box of 20 (plus shipping).
They also have bulk packages as well. This is the lowest price for this ammo that I have seen in a while.
Shipping was a bit expensive, so I would suggest buying a lot if you are interested in maximizing your savings.
