I'm surprised no one mentioned the deal on GGG SS109 ammo from Cheaper Than Dirt this past Monday (3/6/17).
It was $259.00 for a 1000 rnd. case, boxed in an ammo can shipping included!
Knowing how Cheaper Than Dirt can be sometimes I thought it must be a typo, and sure enough, when I tried to order the price appeared at $389.99. When I used their interactive chat to question the error I was told to try again in an hour or so and it would be fixed. "At what price" I asked; the $259.00 with free shipping as advertised? The response said, "Yes, at $259.00."
An hour and a half later I was able to order a case at the $259.00 w/free shipping price. I told three other friends who each ordered a case but it quickly sold out after that. I never got the chance to alert everyone here before it was gone.
That's the cheapest I've seen in many, many years for new production SS109 ammo.
