Funny you should post that. I organized my ammo closet the other day and found a few boxes of Wolf 9mm. I remember when I bought my first hand-gun back in 2007 buying it because it was like $75/500, mite have even been cheaper than that. I miss those days. I also remember buying the Federal bulk packs at Walmart for $11 and there were always 40-50 on the shelf, now they're $20something and you can never find them.I'm thinking Southern Ohio Gun flier circa 2004-2005ish.
In a related note, here are some ammo prices from 2003.
