CDKeys offers Nintendo Store downloads of Mario Kart 7 for Nintendo 3DS
for $19.99. Provide an email address on the CDKey's Facebook page
to get a unique coupon code that drops it to $18.99
. (You don't have to "like" the Facebook page to get the code.) That's $2 below our mention from three weeks ago and and the lowest price we could find by $6 (outside of the deal below).
