RE: 30-40 Krag
Man, that sucks, try using Google, there's other sites that sell ammo, you just have to really look, but you could still find average price ammo there, even some unique things, like this one site had 110 grain .308!
If they have it, I would suggest Federal Powershoks, they are only $10.97 for standard calibers, and they are VERY accurate and POWERful. They can actually be used as hunting rounds, too, though I usually prefer Federal Vital-Shok for hunting, but it's more expensive.
