When ordering online I check gun-deals.com then select the ammo deals option as they give approximate shipping cost when you enter your zip code http://gun-deals.com/list/ammo/9mm+Luger/showall
I buy most of my bulk orders from them. They usually come out ahead on bulk when it comes to the total price including shipping. And their inventory is up to date on their website. So if it says it's in stock, it is.
