Unfortunately shipping is not available at the moment.
This is for those who can't get it at Kmart where it is on clearance for $9.97.
Walmart also has the second (Diabolical Box $9.95) and third games (Unwound Future $13.80) discounted. Unwound Future has been at $11.62 but that was back in December. Oddly enough while they have the 2 for $29 bundle you're better of getting both of them in the NDS 2 for $20 Video Game bundle (with $2.97 shipping). They're both found on the bottom half of the list if you don't wanna browse the 121 eligible games.
Since we're close to the end of the Club Nintendo year, each of the games are worth 30 coins.
Also, if anyone was curious as to the order of the games released in the US, so far it's:
Curious Village (DS)
Diabolical Box (DS)
Unwound Future (DS)
Last Specter (DS)
Miracle Mask (3DS)
