Here is a link to the qualifying game page:
If you can't order it online, I'd suggest checking in store as they tend to have a pretty decent selection.
Thanks to billytwoshoes and straight edge follower for this info:
If you want to buy something more expensive or need filler check your store for Link's Crossbow Training (.49 cents) or Wii Fit (Disc only) as you can buy multiples of those to get you over the 6 threshold. Works great for buying some of the pricier Wii or DS games.
Some highlights IMO:
Dementium I and II:
Touch Detective 1 and 2.5:
Brain Age 1 and 2:
Hotel Dusk: Room 215:
And the list could go on and on.
If you are getting a DS/3DS or know someone who will be getting one for Christmas now would be a good time to stock up. Have a more expensive game in mind? Combine it with some cheap ones and they all get the discount if you meet the number requirements.
It was worth it to me alone for Dementium 1 and 2 (I found 1 online, 2 in store).
