Hah. I don't remember many prices. The guy had way too freaking much ammo for me to memorize the prices!
I do remember he sold all his .45 ACP Ranger T for about $50/box. Almost all of it went to one guy!
I think the Aguila .380 FMJ was $23/box.
.50 BMG tracers for $5 each. 7.62x39mm tracers for $12/bag of 10 (two bags are across the room from me).
