Its new and take around 2 weeks to ship for me.
Do you live in the US?
You can probably get it somewhere cheaper.
Now playing: Super Mario 3D Land(3DS), LoZ: Skyward Sword(Wii), Modern Warfare 3(PS3)
Waiting for: PlayStation Vita, Super Smash Bros. 4(3DS, Wii U), and more.
I got it for $17 or so around the launch of the 3DS (my first 3DS game) and I've put so far 38 hours into it, which is ridiculous considering the price and game length these days. I got into it being a fan of advance wars and while it is similar its more like Fire Emblem or something similar, I really liked the squad based combat and upgrades. The graphics aren't wonderful, I'm fairly sure it was meant to be a DS release and they made it for the 3DS, but the 3D effect is neat and again lots of gameplay to be had. I recommend it for that price, and if you do get it play it on the hardest difficulty, elite or whatever it says. I usually play on normal for most games but someone recommended the game to me and they too played on the hardest difficulty, which isn't THAT hard, it's sometimes challenging but not too easy and I never got completely stumped, so it's a nice level to play on (I think) and I also believe you may get some extra perks for beating levels on hard. Anyway, hope that helps.
