No longer what it used to be. I remember epps had 2280 rd crates for 190$ back in 2007 and no one was buying them as there was few pistols. Now there is more pistols and ammo is almost as expensive as 9mm.
Tradeex on top of the board has Russian crates that have a bit more rounds and free shipping for 499.
So if you gaging selling price, I'd ask some where in 300 range if you want to move it fast.
Asking and getting price is two different things
